ext4: make some fast commit functions reuse extents path
The ext4_find_extent() can update the extent path so that it does not have
to allocate and free the path repeatedly, thus reducing the consumption of
memory allocation and freeing in the following functions:
ext4_ext_clear_bb
ext4_ext_replay_set_iblocks
ext4_fc_replay_add_range
ext4_fc_set_bitmaps_and_counters
No functional changes. Note that ext4_find_extent() does not support error
pointers, so in this case set path to NULL first.
