When sending a query to the device returns with a timeout error,
we clear the corresponding bit in the DOORBELL register but
we don't clear the outstanding_request field as we should.
This patch fixes this bug.

Sometimes queries from the device might return a failure so it is
recommended to retry sending the query, before giving up.
This change adds a wrapper to retry sending a query attribute,
in cases where we need to wait longer, before we continue,

2. What used to be the old platform "probe" is now "only"
a pltfrm_init() routine, that does exactly the same, but only
being called by the new probe function of the UFS variant.

This serie of 15 small patches should be pushed after the series of 8 patches
I have uploaded to the upstream a week ago:
"Fix error message and present UFS variant probe"
Yaniv Gardi (15):
scsi: ufs: clear UTRD, UPIU req and rsp before new transfers
scsi: ufs: clear fields UTRD
When sending a query to the device returns with a timeout error,
we clear the corresponding bit in the DOORBELL register but
we don't clear the outstanding_request field as we should.
This patch fixes this bug.
