block: Fix dev_t minor allocation lifetime
Releases the dev_t minor when all references are closed to prevent
another device from acquiring the same major/minor.
Since the partition's release may be invoked from call_rcu's soft-irq
context, the ext_dev_idr's mutex had to be replaced with a spinlock so
as not so sleep.
