xfs: simplify xfs_map_blocks
No need to lock the extent map exclusive when performing an
overwrite, we know the extent map must already have been loaded by
get_blocks. Apply the non-blocking inode semantics to all mapping
types instead of just delayed allocations. Remove the handling of
not yet allocated blocks for the IO_UNWRITTEN case - if an extent is
marked as unwritten allocated in the buffer it must already have an
extent on disk.
Add asserts to verify all the assumptions above in debug builds.
