When get_hwpoison_page() returns a negative value, distinguish reserved pages from other failure cases by reporting MF_MSG_KERNEL instead of MF_MSG_GET_HWPOISON. Reserved pages belong to the kernel and should be classified accordingly for proper handling by the panic_on_unrecoverable_memory_failure mechanism.
