fault-inject: use prandom where cryptographically secure randomness is not needed
Currently get_random*() is used to determine the probability of fault
injection, but cryptographically secure random numbers are not required.
There is no big problem in using prandom instead of get_random*() to
determine the probability of fault injection, and it also avoids acquiring
a spinlock, which is unsafe in some contexts.
