drm: msm: Check cmd_db_read_aux_data() for failure
We need to check the call to cmd_db_read_aux_data() for the error case,
so that we don't continue and use potentially uninitialized values for
'pri_count' and 'sec_count'. Otherwise, we get the following compiler
warnings:
drivers/gpu/drm/msm/adreno/a6xx_gmu.c: In function 'a6xx_gmu_rpmh_arc_votes_init.isra.12':
drivers/gpu/drm/msm/adreno/a6xx_gmu.c:943:12: warning: 'pri_count' is used uninitialized in this function [-Wuninitialized]
pri_count >>= 1;
^~~
drivers/gpu/drm/msm/adreno/a6xx_gmu.c:948:12: warning: 'sec_count' may be used uninitialized in this function
[-Wmaybe-uninitialized]
sec_count >>= 1;
^~~
