Subject: [PATCH] trace: only build mask up to SPDK_TRACE_MAX_GROUP_ID

Existing implementation worked, but results in a lot of
unnecessary error messages.

Found while debugging nightly iSCSI tests, which generate
a config file from the existing configuration and calls
spdk_trace_get_tpoint_group_mask() to do it.
