[PATCH] Fix for memory allocation in fingerprint.c

This patch fixes an off-by-one memory allocation error in the
printable_fingerprint function of lib/fingerprint.c. The code
sprintf((char *)p, "%02X ", fp[i]); prints a space and terminating null
byte on every call, but no memory was reserved for the null byte.
