pmp_get() may return an error if the given entry, given by the caller of is_pmp_entry_mapped(), is invalid. This results in the output parameters for pmp_get() being uninitialized. To avoid using garbage values, check the result and return early if necessary. This issue is not being hit because at the moment is_pmp_entry_mapped() is only being called from a single site with a valid hardcoded value.
