The options are not conflicting directly, like for the compression and
nodatacow, but it still is related to compression so it does not feel
right to allow that even if it's a noop.

If we'd pass in fs_info to check_fsflags() we could also validate against mount options
which are incompatible with inode flags. Like -o nodatacow and FS_COMPR_FL or
-o auth_key and FS_NOCOW_FL.

Same question was asked on IRC too, mount options are independent and
take lower precedence than the inode attributes. A scenario where user
wants to set a nodatacow attribute when the filesystem is mounted with
compress= is valid and can be quite common.

User Forza reported on IRC that some invalid combinations of file
attributes are accepted by chattr.
The NODATACOW and compression file flags/attributes are mutually
exclusive, but they could be set by 'chattr +c +C' on an empty file. The
nodatacow will be in effect because it's checked first in
btrfs_run_delalloc_range.
Extend the flag validation to catch the following cases:
- input flags are conflicting
- old and new flags are conflicting
- initialize the local variable with inode flags after inode ls locked
Inode attributes take precedence over mount options and are an
independent setting.
Nocompress would be a no-op with nodatacow, but we don't want to mix
any compression-related options with nodatacow.
