f2fs: compress: fix to avoid redundant compress extension
[ Upstream commit 7e1b150fece033703a824df1bbc03df091ea53cc ]
With below script, redundant compress extension will be parsed and added
by parse_options(), because parse_options() doesn't check whether the
extension is existed or not, fix it.
1. mount -t f2fs -o compress_extension=so /dev/vdb /mnt/f2fs
2. mount -t f2fs -o remount,compress_extension=so /mnt/f2fs
3. mount|grep f2fs
/dev/vdb on /mnt/f2fs type f2fs (...,compress_extension=so,compress_extension=so,...)
Fixes: 4c8ff7095bef ("f2fs: support data compression")
Fixes: 151b1982be5d ("f2fs: compress: add nocompress extensions support")
