octeontx2-af: Fix possible buffer overflow

A loop in rvu_mbox_handler_nix_bandprof_free() contains
a break if (idx == MAX_BANDPROF_PER_PFFUNC),
but if idx may reach MAX_BANDPROF_PER_PFFUNC
buffer '(*req->prof_idx)[layer]' overflow happens before that check.

The patch moves the break to the
beginning of the loop.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
