ext4: minor defrag code improvements

Browse source

Modify the error returns for two file types that can't be defragged to
more clearly communicate those restrictions to a caller.  When the
defrag code is applied to swap files, return -ETXTBSY, and when applied
to quota files, return -EOPNOTSUPP.  Move an extent tree search whose
results are only occasionally required to the site always requiring them
for improved efficiency.  Address a few typos.
