osmocom: Address warning about aliasing
We alias the uint8_t buf[..] to a uint16_t* which is violating
the aliases rule of C. Use an explicit memcpy to copy the first
two byte of the buffer. GCC 4.6.2 (debian) is clever enough to
use a normal load does not generate a memcpy call.
osmocon.c: In function ‘un_tool_read’:
osmocon.c:1239:2: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]
