hamradio: Fix wrong assignment of 'bbc->cfg.loopback'
In file hamradio/baycom_epp.c, the baycom_setmode interface, there is a problem with improper use of strstr. Suppose that when modestr="noloopback", both conditions which are 'strstr(modestr,"noloopback")' and 'strstr(modestr,"loopback")' will be true(not NULL), this lead the bc->cfg.loopback variable will be first assigned to 0, and then reassigned to 1. This will cause 'bc->cfg.loopback = 0' will never take effect. That obviously violates the logic of the code, so adjust the order of their execution to solve the problem.
