scsi: mpi3mr: ioctl timeout when disabling/enabling interrupt

Browse source

[ Upstream commit 02ca7da291 ]

As part of Task Management handling, the driver will disable and enable the
MSIx index zero which belongs to the Admin reply queue. During this
transition the driver loses some interrupts and this leads to Admin request
and ioctl timeouts.

After enabling the interrupts, poll the Admin reply queue to avoid
timeouts.
