s390: mark __cpacf_check_opcode() and cpacf_query_func() as __always_inline
Commit e60fb8bf68d4 ("s390/cpacf: mark scpacf_query() as __always_inline")
was not enough to make sure to meet the 'i' (immediate) constraint for the
asm operands.
With CONFIG_OPTIMIZE_INLINING enabled, Laura Abbott reported error
with gcc 9.1.1:
In file included from arch/s390/crypto/prng.c:29:
./arch/s390/include/asm/cpacf.h: In function 'cpacf_query_func':
./arch/s390/include/asm/cpacf.h:170:2: warning: asm operand 3 probably doesn't match constraints
170 | asm volatile(
| ^~~
./arch/s390/include/asm/cpacf.h:170:2: error: impossible constraint in 'asm'
Add more __always_inline to force inlining.
Fixes: 9012d011660e ("compiler: allow all arches to enable CONFIG_OPTIMIZE_INLINING")
