Fix DROUNDUP_LWORK: patch was not fully copied

[foxtran]

Asm before fix: https://godbolt.org/z/dzoTvaoTq

The most interesting lines are 153-154:

         bl      droundup_lwork_
         fcvt    d0, s0

Here, droundup_lwork_ sets d0 register based on integer value in x0 register. Then, fcvt sets d0 fp64 register with value from s0 fp32 register. However, s0 was set to zero (and, actually, never used), so, after this, d0 is 0.0 that breaks computing of memory requirement.

Only these two files are affected.

Bug was introduced by commit 99c1209 (PR #5702)

Fixes #5754

Oops, not sure what happened to #5702 - there appear to be similar differences in the related complex routines. (One of those silly situations where I abused the web interface for PR creating instead of pushing from a local repo due to travelling)
Thanks a lot for spotting and fixing this, I'll follow up with the remaining files in a minute.

Remaining files are OK.

I'm seeing differences in chegvd.f (roundup not used on RWORK(1) in line 322 between a fresh checkout of both OpenBLAS and Reference-LAPACK, and also for the other c & z files from 1203/5702

[martin-frbg]

Absolutely no idea right now how #5702 ended up with a partial commit of the fixes from 1203, as I had copied the entire files from an up-to-date checkout of Reference , no manual edits...
