ext4: fix missing call to trace_ext4_ext_map_blocks_exit
When ext4_ext_handle_uninitialized_extents(), we will directly return
from ext4_ext_map_blocks(). The trace point of
trace_ext4_ext_map_blocks_exit isn't called, and the user doesn't see
any result. This patch tries to fix this problem.
Meanwhile in ext4_ext_handle_uninitialized_extents it returns errors
or the number of allocated blocks. So 'ret' variable can be removed
due to previously modifications.
