rtlwifi: rtl8192cu: Change firmware upload to use block writes
Driver rtl8192cu writes the firmware with 32-bit asynchronous writes. This
design is OK for USB 2.0 adapters, but the current implementation of
xhcu-hcd has a limited ring size, which is exceeded. By converting to
synchronous block writes, this error is avoided.
