MIPS: kernel: Remove $0 clobber from `mult_sh_align_mod'

Remove rubbish $0 clobber added to inline asm within `mult_sh_align_mod'
with the removal of support for GCC versions below 3.4 made with commit
57810ecb581a ("MIPS: Remove GCC_IMM_ASM & GCC_REG_ACCUM macros").

Previously a macro was used that, depending on GCC version, expanded to
either `accum' or $0.  Since the latter choice was only a placeholder to
keep the syntax consistent and the register referred is hardwired, there
is no point in having it here as it has no effect on code generation.
