objtool: whitelist __sanitizer_cov_trace_switch()
it's not really different from e.g. __sanitizer_cov_trace_cmp4(); as it is, the switches that generate an array of labels get rejected by objtool, while slightly different set of cases that gets compiled into a series of comparisons is accepted. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
