RDMA/qedr: Fix srqs xarray initialization

BugLink: https://bugs.launchpad.net/bugs/1858428
[ 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")
