When the ecryptfs_xattr mount option is turned on, the ecryptfs
metadata will be written to xattr via vfs_setxattr, which will
check the WRITE permissions.
However, this will cause denial of permission when creating a
file withoug write permission.
So fix this by calling __vfs_setxattr directly to skip permission
check.
