xfs: unwind xfs_extent_busy_clear
The current structure of xfs_extent_busy_clear that locks the first busy
extent in each AG and unlocks when switching to a new AG makes sparse
unhappy as the lock critical section tracking can't cope with taking the
lock conditionally and inside a loop.
Rewrite xfs_extent_busy_clear so that it has an outer loop only advancing
when moving to a new AG, and an inner loop that consumes busy extents for
the given AG to make life easier for sparse and to also make this logic
more obvious to humans.
