Remove infinite loop from new QC/A SPI driver

It seems that we really don't need and don't want this loop here.
In case of missing FLASH chip, we should get 0x0 from SPI shift in register after the command, because other chips are silent during their CS high.

What's more, it seems that the access to SPI shift in register is somehow locked until the SOC shifts out all previously programmed bits.
That is only a theory after some tests on scope and still needs more tests.
