When we create a directory with enable compression, all file write into
directory will try to compress.But sometimes we may know, new file
cannot meet compression ratio requirements.
We need a nocompress extension to skip those files to avoid unnecessary
compress page test.

In f2fs_fileattr_set(),
if (!fa->flags_valid)
mask &= FS_COMMON_FL;
In this case, we should not allow to set FS_COMPR_FL, instead of BUG_ON.

This patch will not bring significant performance improvements, I test this on
mobile phone, use androbench, the sequential write test case was open file with
O_TRUNC, set write size to 4KB, performance improved about 2%-3%. If write
size set to 32MB, performance improved about 0.5% .

I have done some tests and the results are as expected.
Here is my test method, create a compressed file, and use
In error path of f2fs_write_compressed_pages(), it needs to call
f2fs_compress_free_page() to release temporary page.
