fd_advise always succeeds

[yagehu]

Subject of the issue

Calling fd_advise always succeeds, even with very large offset, length, or a combination of them.

Test case

(module
  (type (;0;) (func))
  (type (;1;) (func (param i32 i32 i32 i32 i32 i64 i64 i32 i32) (result i32)))
  (type (;2;) (func (param i32)))
  (type (;4;) (func (param i32 i64 i64 i32) (result i32)))
  (import "wasi_snapshot_preview1" "path_open" (func $path_open (type 1)))
  (import "wasi_snapshot_preview1" "proc_exit" (func $proc_exit (type 2)))
  (import "wasi_snapshot_preview1" "fd_advise" (func $fd_advise (type 3)))
  (func $_start (type 0)
    (local $err i32)

    (local.set $err
      (call $path_open
        (i32.const 3)
        (i32.const 0)
        (i32.const 1024)
        (i32.const 1)
        (i32.const 0)
        (i64.const 262143)
        (i64.const 262143)
        (i32.const 0)
        (i32.const 512)
      )
    )
    (local.get $err)
    (if
      (then (call $proc_exit (i32.const 1)))
    )

    (local.set $err
      (call $fd_advise
        (i32.load (i32.const 512))
        (i64.const 16942241767661461241)
        (i64.const 9765931924571875679)
        (i32.const 0)
      )
    )
    (local.get $err)
    (if
      (then (call $proc_exit (local.get $err)))
    )

    (call $proc_exit (i32.const 0))
  )
  (memory 2)
  (export "memory" (memory 0))
  (export "_start" (func $_start))
  (data (i32.const 1024) "a\00")
)

Your environment

64-bit x86 Fedora Linux

WAMR is latest HEAD.

Steps to reproduce

Use wat2wasm to encode the above WAT code and run it with iwasm mounting some directory:

$ wat2wasm advise.wat -o advise.wasm
$ iwasm --dir=. advise.wasm
$ echo $?

Expected behavior

It should print some non-zero error code, say 28.

Actual behavior

It prints 0.

Extra Info

I will raise a PR that fixes this.
