btrfs: use cond_resched_rwlock_write() during inode eviction

Browse source 
At evict_inode_truncate_pages(), instead of manually checking if
rescheduling is needed, then unlock the extent map tree, reschedule and
then write lock again the tree, use the helper cond_resched_rwlock_write()
which does all that.
