ntfs: leave HasEA flag untouched on setxattr failure

Browse Source 
In ntfs_set_ea(), the exit path unconditionally updates the HasEA
flag based on ea_info_qsize. When an error occurs before
ea_info_qsize is updated, NInoClearHasEA() hides existing on-disk
EAs until the inode is evicted.

Only update the flag on success.
