spi: pl022: update outdated references to pump_transfers()

The pump_transfers tasklet was removed when the driver
switched to the SPI core message processing loop in commit
9b2ef250b31d ("spi: spl022: switch to use default
spi_transfer_one_message()").  The kdoc of
pl022_interrupt_handler() still describes the old flow: scheduling
the pump_transfers tasklet, calling giveback(), and flagging
STATE_ERROR — none of which exist in the current code.  Rewrite
the kdoc to reflect the current paths, which flag errors via
SPI_TRANS_FAIL_IO and call spi_finalize_current_transfer()
directly.
