Subject: iw_cxgb4: make pointer reg_workq static
Patch-mainline: v4.16-rc1
Git-commit: 0cb65d421a2ad714d336e673d448184ea51bb66a
References: bsc#1064802 bsc#1066129

The pointer reg_workq is local to the source and does not need to be
in global scope, so make it static.

Cleans up sparse warning:
drivers/infiniband/hw/cxgb4/device.c:69:25: warning: symbol 'reg_workq'
was not declared. Should it be static?

Fixes: 1c8f1da5d851 ("iw_cxgb4: Fix possible circular dependency locking warning")
