Subject[PATCH AUTOSEL 5.4 173/350] RDMA/qedr: Fix srqs xarray initialization
Date
From: Michal Kalderon <michal.kalderon@marvell.com>

[ Upstream commit 73ab512f720298aabe23b34110e3f6a8545b0ba5 ]

There was a missing initialization for the srqs xarray.
SRQs xarray can also be called from irq context when searching
for an element and uses the xa_XXX_irq apis, therefore should
be initialized with IRQ flags.

Fixes: 9fd15987ed27 ("qedr: Convert srqidr to XArray")
