spi: zynq-qspi: Replace kzalloc with kmalloc for buffer allocation
In zynq_qspi_exec_mem_op(), the temporary buffer is allocated with
kzalloc and then immediately initialized using memset to 0xff. To
optimize this, replace kzalloc with kmalloc, as the zeroing operation
is redundant and unnecessary.
