spi: nxp-fspi: Use reinit_completion() for repeated operations
The driver currently calls init_completion() during every spi_mem_op. Tchnically it may work, but it's not the recommended pattern. According to the kernel documentation: Calling init_completion() on the same completion object twice is most likely a bug as it re-initializes the queue to an empty queue and enqueued tasks could get "lost" - use reinit_completion() in that case, but be aware of other races. So moves the initial initialization to probe function and uses reinit_completion() for subsequent operations.
