[PATCH] habanalabs: remove variable 'val' set but not used

[Chen Wandun]

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/misc/habanalabs/goya/goya.c: In function goya_pldm_init_cpu:
drivers/misc/habanalabs/goya/goya.c:2195:6: warning: variable val set but not used [-Wunused-but-set-variable]
drivers/misc/habanalabs/goya/goya.c: In function goya_hw_init:
drivers/misc/habanalabs/goya/goya.c:2505:6: warning: variable val set but not used [-Wunused-but-set-variable]

Fixes: 9494a8dd8d22 ("habanalabs: add h/w queues module")
