[RFC PATCH 01/41] random: remove dead code in credit_entropy_bits()

[Nicolai Stange]

Since commit 90ea1c6436d2 ("random: remove the blocking pool") the local
has_initialized in credit_entropy_bits() won't get set anymore and
the corresponding if-clause became dead code. Remove it as well as the
has_initialized variable itself from credit_entropy_bits().
