fix(bsp/rp2040): use MAX3421_SPI in spi_write_read_blocking
The write+read path in tuh_max3421_spi_xfer_api() hardcodes spi0
instead of using the MAX3421_SPI define. This causes a hang on
boards wired to spi1 (e.g. Feather RP2040 USB Host + MAX3421E
FeatherWing) since spi_write_read_blocking() blocks forever on an
uninitialized SPI peripheral.
The read-only and write-only paths already use MAX3421_SPI correctly.
