fix: amplify io is too large to hold in fuse buffer

[ccx1024cc]

Fuse request buffer is fixed by FUSE_KERN_BUF_SIZE * pagesize() + FUSE_HEADER_ SIZE. When amplify io is larger than it, FuseDevWriter suffers from smaller buffer. As a result, invalid data error is returned.

Reproduction

run nydusd with 3MB amplify_io
error from random io:
    reply error header OutHeader { len: 16, error: -5, unique: 108 }, error Custom { kind: InvalidData, error: "data out of range, available 1052656 requested 1250066" }

Details

size of fuse buffer = 1052656 + 16 (size of inner header) = 256(FUSE_KERN_BUF_SIZE) * 4096(page size) + 4096(fuse header)
let amplify_io = min(user_specified, fuseWriter.available_bytes())

Resolution

Evalucation of amplify_io will be replaced with ZeroCopyWriter.available_bytes().
