[PATCH AUTOSEL 4.14 08/27] IB/{qib, hfi1, rdmavt}: Correct ibv_devinfo max_mr value

[Sasha Levin <sashal@kernel.org>]

From: Mike Marciniszyn <mike.marciniszyn@intel.com>

[ Upstream commit 35164f5259a47ea756fa1deb3e463ac2a4f10dc9 ]

The command 'ibv_devinfo -v' reports 0 for max_mr.

Fix by assigning the query values after the mr lkey_table has been built
rather than early on in the driver.

Fixes: 7b1e2099adc8 ("IB/rdmavt: Move memory registration into rdmavt")
