ANDROID: Fix race in crng_reseed()

The crng_init triggers process_crng_rdy_callbacks() and those callbacks
can call into the crng again. So, leave the spinlock before processing
the callbacks.

This is a version of upstream commit '4a072c71f49b'

Bug: 124090075
Test: Build and boot cuttlefish with hwrng enabled
