[PATCH] spi: xlp: reinitialize completion before each transfer block

[Felix Gu]

Reinitialize the completion before each transfer block to prevent
wait_for_completion_timeout() from returning immediately on a stale
completion count left by a prior transfer block.

Fixes: d8c80d49cfa0 ("spi/xlp: SPI controller driver for Netlogic XLP SoCs")
