can: ti_hecc: ti_hecc_mailbox_read(): remove set but not used variable 'mbx_mask'

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

drivers/net/can/ti_hecc.c: In function 'ti_hecc_mailbox_read':
drivers/net/can/ti_hecc.c:533:12: warning:
 variable 'mbx_mask' set but not used [-Wunused-but-set-variable]

It is never used so can be removed.
