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.
