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: 7f5933f81bd8 ("x86/asm: Add an enqcmds() wrapper for the ENQCMDS instruction")
