The mpi_uninit_check() takes longer for inbound doorbell register to be
cleared. Increased 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 the 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.

Fixes: e90e236250e9 ("scsi: pm80xx: Increase timeout for pm80xx
mpi_uninit_check")

Noticed missing semicolons. Sent v2 to fix this issue.
