Seems that some hf with the same fieldname
(btsdp.service_uuid in this case) may contain incompatible options
(FT_BYTES and FT_UINT16 in this case). When filtering with
"btsdp.service_uuid==5" everything is ok, but "btsdp.service_uuid==0x5" cause
the crash. 

Patch: Change fieldname to avoid crash.

Maybe issue like this should be detected by tools/checkfiltername.pl or
tools/checkhf.pl (other?)
