Increase the timeout substantially so that the driver does not fail to load. Previously, the inbound doorbell wait time was mistakenly increased in the mpi_init_check() instead of mpi_uninit_check(). It is okay to leave the mpi_init_check() wait time as-is as these are timeout values and if there is a failure, waiting longer is not an issue.
