prefs: fix range preferences-related crash after switching profiles
The HTTP dissector could crash (use-after-free) after switching
profiles. In reinit_http, it would assign the return value from
prefs_get_range_value to a global variable which is consulted during
dissection. This value is invalidated while switching profiles (via the
"prefs_reset" function), but is not reinitialized (because the
reinit_http function was not called).
A similar issue exists in the Kafka, UAUDP, VNC, TFTP, Gopher and TDS
dissectors. To reproduce using a capture from the SampleCaptures wiki,
start "wireshark -r vnc-sample.pcap -ovnc.tcp.port:1" and switch
profiles. For the HTTP crash, load any HTTP pcap and switch profiles.
