kcov: mark in_softirq_really() as __always_inline
If gcc decides not to inline in_softirq_really(), objtool warns about a
function call with UACCESS enabled:
kernel/kcov.o: warning: objtool: __sanitizer_cov_trace_pc+0x1e: call to in_softirq_really() with UACCESS enabled
kernel/kcov.o: warning: objtool: check_kcov_mode+0x11: call to in_softirq_really() with UACCESS enabled
Mark this as __always_inline to avoid the problem.
