platform/x86/amd/pmf: Fix unsigned comparison with less than zero
[ Upstream commit 785c00993dc4c4bb2f7b0f3a3f29c03a6f7aab2e ]
The return value from the call to amd_pmf_get_pprof_modes() is int.
However, the return value is being assigned to an unsigned char
variable 'mode', so making 'mode' an int.
silence the warning:
