Paul Burton f229454d34 MIPS: Fix protected_cache(e)_op() for microMIPS
When building for microMIPS we need to ensure that the assembler always
knows that there is code at the target of a branch or jump. Commit
7170bdc777 ("MIPS: Add return errors to protected cache ops")
introduced a fixup path to protected_cache(e)_op() which does not meet
this requirement. The fixup path jumps to the "2" label but the .section
pseudo-op immediately following it causes the label to be marked as
data. Linking then fails with:

  mips-img-linux-gnu-ld: arch/mips/mm/c-r4k.o: .fixup+0x0: Unsupported
  jump between ISA modes; consider recompiling with interlinking
  enabled.

Fix this by declaring that "2" labels code using the .insn directive.
