[PATCH 5.9 133/152] RDMA/hns: Fix wrong field of SRQ number the device supports

[Greg Kroah-Hartman]

From: Wenpeng Liang <liangwenpeng@xxxxxxxxxx>

[ Upstream commit ebed7b7ca47f3aa95ebf2185a526227744616ac1 ]

The SRQ capacity is got from the firmware, whose field should be ended at
bit 19.

Fixes: ba6bb7e97421 ("RDMA/hns: Add interfaces to get pf capabilities from firmware")
