ext4: fix memory leak in ext4_ext_shift_extents()
commit ca81109d4a8f192dc1cbad4a1ee25246363c2833 upstream.
In ext4_ext_shift_extents(), if the extent is NULL in the while loop, the
function returns immediately without releasing the path obtained via
ext4_find_extent(), leading to a memory leak.
Fix this by jumping to the out label to ensure the path is properly
released.
Fixes: a18ed359bdddc ("ext4: always check ext4_ext_find_extent result")
