qca_spi: Fix reset behavior
In case of a reset triggered by the QCA7000 itself, the behavior of the
qca_spi driver was not quite correct:
- in case of a pending RX frame decoding the drop counter must be
incremented and decoding state machine reseted
- also the reset counter must always be incremented regardless of sync
state
