lchan2lch_par(): fix missing default branch in switch

New channel mode values have recently been added with change [1]
to 'enum gsm48_chan_mode'.  The lack of default branch in
lchan2lch_par() caused build failures on Jenkins:

  oml.c:956:2: error: enumeration value ‘GSM48_CMODE_SPEECH_V2_VAMOS’
                      not handled in switch [-Werror=switch]
  oml.c:956:2: error: enumeration value ‘GSM48_CMODE_SPEECH_V3_VAMOS’
                      not handled in switch [-Werror=switch]
  oml.c:956:2: error: enumeration value ‘GSM48_CMODE_SPEECH_V5_VAMOS’
                      not handled in switch [-Werror=switch]

This function is duplicated in osmo-bts-{lc15,oc2g,octphy,sysmo},
so we unfortunately need to apply the same fix to all copy-pasted files.
