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.
