[ Upstream commit 0d2e7c840b178bf9a47bd0de89d8f9182fa71d86 ]
The function nvme_alloc_request() is called from different context
(I/O and Admin queue) where callers do not consider the I/O timeout when
called from I/O queue context.
Update nvme_alloc_request() to set the default I/O and Admin timeout
value based on whether the queuedata is set or not.
