Subject: [PATCH -next] f2fs: fix build error too many arguments to functions

If CONFIG_F2FS_FS_COMPRESSION is not set.

make ARCH=x86_64 CROSS_COMPILE=x86_64-linux-gnu-, will be failed, like this:

Since commit 1b565702dffe ("f2fs: handle decompress only post processing in softirq") 
had changed the definition of function "f2fs_end_read_compressed_page()" and "f2fs_put_page_dic()",
but forgot the other definitions in f2fs.h warpped by #else /* CONFIG_F2FS_FS_COMPRESSION */.
