ext4: Avoid underflow in ext4_trim_fs()
commit 5de35e8d5c02d271c20e18337e01bc20e6ef472e upstream.
Currently if len argument in ext4_trim_fs() is smaller than one block,
the 'end' variable underflow. Avoid that by returning EINVAL if len is
smaller than file system block.
Also remove useless unlikely().
