Fix inline extent handling in btrfs_get_extent
1. Reorder kmap and the test for 'page != NULL'
2. Zero-fill rest area of a block when inline extent isn't big enough.
3. Do not insert extent_map into the map tree when page == NULL.
(If insert the extent_map into the map tree, subsequent read requests
will find it in the map tree directly and the corresponding inline
extent data aren't copied into page by the the get_extent function.
extent_read_full_page can't handle that case)
