remoteproc: qcom_wcnss: Fix handling the lack of PD regulators in v3

Browse source

The changes introduced to handle single power domain platforms have
swapped the info pointer increment from num_pd_vregs to num_pds, which
would shift the info pointer past the end of the array for pronto-v3,
which does not list power domain regulators in vregs.

This showed up as a difference between GCC- and LLVM-compiled kernels
on SDM632 devices, where only with LLVM one would get the
"regulator request with no identifier" error, because the out-of-bounds
memory ended up being zeroed. Fix by skipping the increment when there
are more power domains than regulators.
