md: fix sync_action incorrect display during resync
During raid resync, if a disk becomes faulty, the operation is
briefly interrupted. The MD_RECOVERY_RECOVER flag triggered by
the disk failure causes sync_action to incorrectly show "recover"
instead of "resync". The same issue affects reshape operations.
Reproduction steps:
mdadm -Cv /dev/md1 -l1 -n4 -e1.2 /dev/sd{a..d} // -> resync happened
mdadm -f /dev/md1 /dev/sda // -> resync interrupted
cat sync_action
-> recover
Add progress checks in md_sync_action() for resync/recover/reshape
to ensure the interface correctly reports the actual operation type.
Fixes: 4b10a3bc67c1 ("md: ensure resync is prioritized over recovery")
