spi: spi-mem: avoid mutating op template in spi_mem_supports_op()
spi_mem_supports_op() accepts a const struct spi_mem_op pointer but
casts away const internally to call spi_mem_adjust_op_freq(). This
mutates the caller's op template, which causes stale max_freq values
when callers reuse persistent templates - subsequent calls won't
re-apply the device frequency cap since spi_mem_adjust_op_freq()
skips non-zero values.
Fix by operating on a stack-local copy instead.
