fscrypt: switch from ->is_encrypted() to IS_ENCRYPTED()

Browse Source 
IS_ENCRYPTED() now gives the same information as
i_sb->s_cop->is_encrypted() but is more efficient, since IS_ENCRYPTED()
is just a simple flag check.  Prepare to remove ->is_encrypted() by
switching all callers to IS_ENCRYPTED().
