[PATCH V5 2/7] nvme-core: use I/O timeout in nvme_submit_user_cmd

[Chaitanya Kulkarni]

In the function nvme_submit_user_cmd() it uses ADMIN_TIMEOUT when
caller doesn't specify value for the timeout variable. This function is
also called from the user I/O command contexts (nvme_submit_io,
nvme_user_cmd_XXX) where NVME_IO_TIMEOUT can be used instead of
ADMIN_TIMEOUT.

For now we don't set the request queue's queuedata for admin command.

Use newly introduced helper function nvme_default_timeout() to set the
block layer request timeout value.
