Fixed incoming calls being matched to MSNs without type-of-number prefix added.

For an incoming ISDN call the dialed.number is incorrectly matched against
the configured MSNs in misdn.conf.  The numbers passed to the dialplan
include the configured prefix for the dialed.number_type, whereas the
check against the configured MSNs (to decide if the call is accepted at
all), is executed without the configured prefix.

e.g., dialed.number = 241168020, TON = national, configured national
prefix is "0".  (This is the TON which is used by ISDN providers in the
Netherlands.)

In chan_misdn.c:cb_events() in case EVENT_SETUP the call to
misdn_cfg_is_msn_valid() uses the unnormalized number 241168020, but 57
lines later the call to read_config() adds the prefix, and the
dialed.number is now 0241168020, which is then used in the dialplan.
misdn_cfg_is_msn_valid() must use the normalized number, too.
