Subject: [PATCH net v2 3/4] bnxt_en: Fix wrong return value check in bnxt_close_nic()

From: Kalesh AP <kalesh-anakkur.purayil@...adcom.com>

The wait_event_interruptible_timeout() function returns 0
if the timeout elapsed, -ERESTARTSYS if it was interrupted
by a signal, and the remaining jiffies otherwise if the
condition evaluated to true before the timeout elapsed.

Driver should have checked for zero return value instead of
a positive value.

Fixes: c0c050c58d84 ("bnxt_en: New Broadcom ethernet driver.")
