[PATCH] perf test: Silence perf check subcommand when not supported

[Thomas Richter <tmricht@linux.ibm.com>]

Perf subcommand check might not be supported and prints an
error message when used:

 # perf check feature -q libtraceevent
 perf: 'check' is not a perf-command. See 'perf --help'.

 Did you mean one of these?
        c2c
        sched
 #

Drop this error message, the return code is sufficient.
