x86/asm: Fix SETZ size enqcmds() build failure 



When building under GCC 4.9 and 5.5:

  arch/x86/include/asm/special_insns.h: Assembler messages:
  arch/x86/include/asm/special_insns.h:286: Error: operand size mismatch for `setz'

Change the type to "bool" for condition code arguments, as documented.

Fixes: 7f5933f8 ("x86/asm: Add an enqcmds() wrapper for the ENQCMDS instruction")
