Subject: mips/kprobes: export kprobe_fault_handler()

Generic kprobe_page_fault() calls into kprobe_fault_handler() which must
be available with and without CONFIG_KPROBES.  There is one stub
implementation for !CONFIG_KPROBES.  For CONFIG_KPROBES all subscribing
archs must provide a kprobe_fault_handler() definition.  Currently mips
has an implementation which is defined as 'static inline'.  Make it
available for generic kprobes to comply with the above new requirement.
