mtd: m25p80: Use SPI_MEM_OP_NO_DUMMY instead of SPI_MEM_OP_DUMMY(0, x)
SPI_MEM_OP_DUMMY(0, x) means there's 0 dummy bytes to send, which is
similar to SPI_MEM_OP_NO_DUMMY except it's less clear. Use
SPI_MEM_OP_NO_DUMMY instead of SPI_MEM_OP_DUMMY(0, x) in
m25p80_write().
Also stop updating op.dummy.buswidth since this value is only
meaningful if you have dummy bytes.
