spi: spi-rspi: Drop redeclaring ret variable in qspi_transfer_in()

"ret" variable is already declared in qspi_transfer_in() at the
beginning of function, drop redeclaring ret in the if block, fixing
below:

spi-rspi.c: In function ‘qspi_transfer_in’:
spi-rspi.c:838:7: warning: declaration of ‘ret’ shadows a previous local
  838 |   int ret = rspi_dma_transfer(rspi, NULL, &xfer->rx_sg);
      |       ^~~
spi-rspi.c:835:6: note: shadowed declaration is here
  835 |  int ret;
