Subject: [PATCH] Fix some minor inconsistencies in LAPACK(E)_[cz]gesvdq

For LAPACKE_cgesvdq, align datatype of `rwork` with lapacke.h and callsite
in LAPACKE_cgesvdq_work; both of the latter use `float* rwork`, so there's
no need to calculate with doubles that only get downcast anyway.

Similarly, make the signature of lapacke_zgesvdq_work consistent across
lapack.h (modified here), the fortran side and lapacke_zgesvdq_work, see:
https://github.com/Reference-LAPACK/lapack/blob/v3.9.0/LAPACKE/src/lapacke_zgesvdq_work.c#L42
