[SPARC64]: Fix fault handling in unaligned trap handler.
We were not calling kernel_mna_trap_fault() correctly.
Instead of being fancy, just return 0 vs. -EFAULT from
the assembler stubs, and handle that return value as
appropriate.
Create an "__retl_efault" stub for assembler exception
table entries and use it where possible.
