nvme-core: fix unsigned comparison warning in nvme_wait_freeze_timeout

Browse Source 
The timeout variable in nvme_wait_freeze_timeout() is an unsigned type.
Checking if it is <= 0 triggers a compiler warning because an unsigned
variable can never be negative.

Fix this warning by changing the type to long.
