Patrick McHardy 4e04c104d1 libdect: don't reseed PRNG on dect_open_handle() 
Move seeding to an __init function to avoid reseeding the PRNG multiple
times with the same seed when opening multiple handles in a short amount
of time.

While at it, switch from rand() to random() since it uses a better
PRNG in old libcs and non-Linux systems.
