f2fs: compress: fix to disallow temp extension

Browse source

This patch restricts to configure compress extension as format of:

 [filename + '.' + extension]

rather than:

 [filename + '.' + extension + (optional: '.' + temp extension)]

in order to avoid to enable compression incorrectly:

1. compress_extension=so
2. touch file.soa
3. touch file.so.tmp
