PATCH 1/1 parisc: additionally check for in_atomic() in page fault handler

Craig Estey noticed that we didn't checked for in_atomic() in our page fault handler like other architectures. This commit adds this check by using faulthandler_disabled() which includes a check for pagefault_disabled() and in_atomic().
