mgcp: Fix (again) osmux_cid_bitmap static array size calculation
A previous commit merged today fixed array size boundary (multiple of 8 bits), but removed a required +1 which should be kept on top, because OSMUX_CID_MAX specified the maximum number used by a CID, that is (0,OSMUX_CID_MAX), and as a result we require OSMUX_CID_MAX+1 slots. Fixes: 65f422ad5878165be0a1eb05605aa3099536f0c8 Change-Id: I182c9c1a6dd28a4c5c0d8107d53852cf47541592
