Bluetooth: sco: new getsockopt options BT_SNDMTU/BT_RCVMTU

Browse source 
This patch defines new getsockopt options BT_SNDMTU/BT_RCVMTU
for SCO socket to be compatible with other bluetooth sockets.
These new options return the same value as option SCO_OPTIONS
which is already present on existing kernels.
