Subject: [PATCH -next] rapidio: fix -Wunused-const-variable= warning

When building with W=1, the following warning occurs.

drivers/rapidio/rio_cm.c: In function ‘rio_txcq_handler’:
drivers/rapidio/rio_cm.c:673:7: warning: variable ‘rc’ set but not used [-Wunused-but-set-variable]
   int rc;

Since the variable "rc" is not used in function 'rio_txcq_handler',
so we removed it to remove the warning.

Fixes: b6e8d4aa1110 ("rapidio: add RapidIO channelized messaging driver")
