Subject: [PATCH net 2/3] bnxt_en: Fix error recovery for RoCE ulp client

From: Vikas Gupta <vikas.gupta@...adcom.com>

Since runtime MSIXs vector allocation/free has been removed,
the L2 driver needs to repopulate the MSIX entries for the
ulp client as the irq table may change during the recovery
process.

Fixes: 303432211324 ("bnxt_en: Remove runtime interrupt vector allocation")
