ax25ipd: Fix warning and potential buffer overflow in bpqether.c.

Adding an additional check convinces GCC 11 there won't be a buffer
overflow.  Reading the code it's pretty hard to convince myself overflow
is impossible so just suck it up and throw a potentially pointless check
into the spaghetti.

gcc -DHAVE_CONFIG_H -I. -I..  -DAX25_SYSCONFDIR=\""/usr/local/etc/ax25"\" -DAX25_LOCALSTATEDIR=\""/usr/local/var/ax25"\"   -g -O2 -Wall -MT bpqether.o -MD -MP -MF .deps/bpqether.Tpo -c -o bpqether.o bpqether.c
