[PATCH][next] staging: greybus: Remove redundant variable 'mask'

[Colin Ian King <colin.i.king@gmail.com>]

The variable mask is being assigned and bit-set but it is never
being used apart from this. The variable is redundant and can
be removed.

Cleans up clang scan build warning:
drivers/staging/greybus/audio_topology.c:764:15: warning: variable 'mask'
set but not used [-Wunused-but-set-variable]
