s390: mark __cpacf_query() as __always_inline

arch/s390/kvm/kvm-s390.c calls on several places __cpacf_query() directly,
which makes it impossible to meet the "i" constraint for the asm operands
(opcode in this case).

As we are now force-enabling CONFIG_OPTIMIZE_INLINING on all
architectures, this causes a build failure on s390:

   In file included from arch/s390/kvm/kvm-s390.c:44:
   ./arch/s390/include/asm/cpacf.h: In function '__cpacf_query':
   ./arch/s390/include/asm/cpacf.h:179:2: warning: asm operand 3 probably doesn't match constraints
     179 |  asm volatile(
         |  ^~~
   ./arch/s390/include/asm/cpacf.h:179:2: error: impossible constraint in 'asm'

Mark __cpacf_query() as __always_inline in order to fix that, analogically
how we fixes __cpacf_check_opcode(), cpacf_query_func() and scpacf_query()
already.
