Wait for WIP to clear before returning from erase operations too.
Wrong-block-type race condition errors went away after adding the WIP check after flash write operations, then came back once (isolated incident) while running a series of tests which had written enough flash blocks that ks_flash may have finally had to erase something rather than just zeroing. Code inspection confirmed that the erase code was not waiting for WIP to clear before exiting. Difficult to prove that this was the cause of an unreproducible failure, but seems like a likely candidate given previous behavior and change should be harmless, so adding it. Timeout for this flag check is 2000 ms, which is what other erase-related WIP flag checks were already using.
