md/raid1,raid10: fix deadlock in read error recovery path

In the Linux kernel, the following vulnerability has been resolved:

md/raid1,raid10: fix deadlock in read error recovery path

raid1d and raid10d may resubmit a split md cloned bio while handling
a read error. In this case, resubmitting the bio can lead to a deadlock
if the array is suspended before md_handle_request() acquires an
active_io reference via percpu_ref_tryget_live().

Since the cloned bio already holds an active_io reference,
trying to acquire another reference via percpu_ref_tryget_live()
can lead to a deadlock while the array is suspended.

Fix this by using percpu_ref_get() for md cloned bios.
