ext4: fix the comment describing ext4_ext_search_right()
The comment describing what ext4_ext_search_right() does is incorrect. We return 0 in *phys when *logical is the 'largest' allocated block, not smallest. Fix a few other typos while we're at it. Cc: "Theodore Ts'o" <tytso@mit.edu> Signed-off-by: Tao Ma <boyu.mt@taobao.com>
