ext4: copy i_flags to inode flags on write

Browse Source 
Propagate flags such as S_APPEND, S_IMMUTABLE, etc. from i_flags into
ext4-specific i_flags.  Quota code changes these flags on quota files
(to make it harder for sysadmin to screw himself) and these changes were
not correctly propagated into the filesystem.

(This is a forward port patch from ext3)
