kcov: mark in_softirq_really() as __always_inline
commit cb0ca08b326aa03f87fe94bb91872ce8d2ef1ed8 upstream.
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.

Fixes: 7d4df2dad312 ("kcov: properly check for softirq context")
