[SRU][J:linux-bluefield][PATCH v1 09/14] platform/mellanox: mlxbf-pmc: fix signedness bugs

[Shravan Kumar Ramani]

From: Dan Carpenter <dan.carpenter at linaro.org>

BugLink: https://bugs.launchpad.net/bugs/2103611

These need to be signed for the error handling to work.  The
mlxbf_pmc_get_event_num() function returns int so int type is correct.

Fixes: 1ae9ffd303c2 ("platform/mellanox: mlxbf-pmc: Cleanup signed/unsigned mix-up")
