x86/paravirt: Standardize 'insn_buff' variable names
We currently have 6 (!) separate naming variants to name temporary instruction buffers that are used for code patching: - insnbuf - insnbuff - insn_buff - insn_buffer - ibuf - ibuffer These are used as local variables, percpu fields and function parameters. Standardize all the names to a single variant: 'insn_buff'.
