Hello build bot (Jenkins), Nico Huber, Nikolai Artemiev,

writeprotect_ranges.c: Check for underflow when using unsigned types

size_t is an unsigned type so bp_max-2 causes an underflow. This results
in undefined behaviour. So assert before that bits->bp_bit-count > 1 so
that bp_max has a minimum value of 2.
