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.

Changes in v3:
- Fixed the commit message.
Changes in v2:
- Used BT_SNDMTU/BT_RCVMTU instead of creating a new opt name.
- Used the existing conn->mtu instead of creating a new member
in struct sco_pinfo.
- Noted that the old SCO_OPTIONS in sco_sock_getsockopt_old()
would just work as it uses sco_pi(sk)->conn->mtu.
