qed: Wait for ready indication before rereading the shmem

[ Upstream commit f00d25f3154b676fcea4502a25b94bd7f142ca74 ]

The MFW might be reset and re-update its shared memory.
Upon the detection of such a reset the driver rereads this memory, but it
has to wait till the data is valid.
This patch adds the missing wait for a data ready indication.
