mgcp: Fix compiler warning on 64bit builds

ENDPOINT_NUMBER takes the difference of two pointers. On 64bit
builds the difference is a long and the compiler then complains
about the usage of abs. We will never have thousands of endpoints
so silence the warning by casting the ENDPOINT_NUMBER to int.

mgcp_vty.c:1381:34: warning: absolute value function 'abs' given an argument of type 'long' but has parameter of
      type 'int' which may cause truncation of value [-Wabsolute-value]
                        rtp_port = rtp_calculate_port(ENDPOINT_NUMBER(endp),
                                                      ^
