[dpdk-dev] [PATCH] net/bnxt: fix to cancel recovery alarm in port close

[Kalesh A P]

From: Kalesh AP <kalesh-anakkur.pura...@broadcom.com>

There is a race condition when port is closed while error recovery
is happening in driver. Fixed this by canceling the recovery threads
during port close.

Fixes: df6cd7c1f73a (net/bnxt: handle reset notify async event from FW)
