net: qca_spi: Avoid high load if QCA7000 is not available
In case the QCA7000 is not available via SPI (e.g. in reset),
the driver will cause a high load. The reason for this is
that the synchronization is never finished and schedule()
is never called. Since the synchronization is not timing
critical, it's safe to drop this from the scheduling condition.
