The POE frame record is allocated unconditionally if POE is supported. If the allocation fails, a SIGSEGV is delivered before setup_sigframe() can be reached. As a result there is no need to consider poe_offset before saving POR_EL0; just remove that check. This is in line with other frame records (FPMR, TPIDR2).
