spi: fix finalize message on error return

spi: fix finalize message on error return

In __spi_pump_transfer_message(), the message was not finalized in the
first error return as it is in the other error return paths. Not
finalizing the message could cause anything waiting on the message to
complete to hang forever.

This adds the missing call to spi_finalize_current_message().

Fixes: ae7d2346dc89 ("spi: Don't use the message queue if possible in spi_sync")
