habanalabs: remove set but not used variable 'qman_base_addr'

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

drivers/misc/habanalabs/goya/goya.c: In function 'goya_init_mme_cmdq':
drivers/misc/habanalabs/goya/goya.c:1536:6: warning:
 variable 'qman_base_addr' set but not used [-Wunused-but-set-variable]

It is never used, so can be removed.
