Tom Rix 5c6bfde245 fpga: machxo2-spi: Return an error on failure ...

[ Upstream commit 34331739e19fd6a293d488add28832ad49c9fc54 ]

Earlier successes leave 'ret' in a non error state, so these errors are
not reported. Set ret to -EINVAL before going to the error handler.

This addresses two issues reported by smatch:
drivers/fpga/machxo2-spi.c:229 machxo2_write_init()
  warn: missing error code 'ret'

drivers/fpga/machxo2-spi.c:316 machxo2_write_complete()
  warn: missing error code 'ret'
