When arizona_request_irq() returns an error code, a
pairing runtime PM usage counter decrement is needed
to keep the counter balanced. For error paths after
this function, things are the same.
Also, remove calls to pm_runtime_disable() when
pm_runtime_enable() has not been executed.

Normally waiting for a page to become unlocked, or locking the page,
requires waiting for IO to complete. Add support for lock_page_async()
and wait_on_page_locked_async(), which are callback based instead. This
allows a caller to get notified when a page becomes unlocked, rather
than wait for it.
As read-ahead is opportunistic, don't block for request allocation.

Three minor fixes, two in drivers, one to fix a hang after reset with
iSCSI, and one to avoid a spurious log message; and the final core one
