f2fs: fix to enable compress for newly created file if extension matches

[ Upstream commit 787caf1bdcd9f04058e4e8d8ed56db1dbafea0b7 ]

If compress_extension is set, and a newly created file matches the
extension, the file could be marked as compression file. However,
if inline_data is also enabled, there is no chance to check its
extension since f2fs_should_compress() always returns false.

This patch moves set_compress_inode(), which do extension check, in
f2fs_should_compress() to check extensions before setting inline
data flag.
