MIPS: mm: Fix duplicate "const" on insn_table_MM

Fix the following gcc 7.x build error on microMIPS builds:

arch/mips/mm/uasm-micromips.c:43:26: error: duplicate ‘const’ declaration specifier [-Werror=duplicate-decl-specifier]
static const struct insn const insn_table_MM[insn_invalid] = {
^~~~~

The same issue has already been fixed in uasm-mips by commit
00e06297b351 ("MIPS: mm: remove duplicate "const" qualifier on
insn_table").
