fix build with gcc 10
Define curr_state as extern in nanocom.h to avoid the following build
failure with gcc 10 (which defaults to -fno-common):
/home/buildroot/autobuild/instance-3/output-1/host/lib/gcc/arm-buildroot-linux-gnueabihf/10.2.0/../../../../arm-buildroot-linux-gnueabihf/bin/ld: /tmp/ccLQeiek.o:(.bss+0x7c): multiple definition of `curr_state'; /tmp/ccse155z.o:(.bss+0x0): first defined here
Fixes:
