The row-major path hardcoded `lda_t = MAX(1,k)`, which is only correct
when SIDE='L' (A is K-by-N). When SIDE='R', A is M-by-K and the
transposition dimensions, allocation, and leading-dimension checks were
all wrong.

- Introduce nrowsA/ncolsA/nrowsV determined by SIDE (following the
  same pattern as the LAPACKE_?tpmqrt_work fix in PR Reference-LAPACK#540).
- lda_t now uses nrowsA instead of always k.
- lda check compares against ncolsA instead of always m.
- A transpose uses (nrowsA, ncolsA) instead of (k, m).
- LDV check depends on STOREV: ldv >= nrowsV for STOREV='C',
  ldv >= k for STOREV='R'.
- V transpose uses nrowsV rows instead of ldv.

Closes Reference-LAPACK#734
