msm_serial_hs: Deregister UART bus client in error path
msm_serial_hs: Deregister UART bus client in error path

Currently probe() doesn't deregister UART bus client if
trying to get any other resource fails. With that memory
corruption is seen as bus driver is still having reference
to pdata allocated for UART bus client and if same memory
is re-used before msm_bus_debugfs_init is called. Fix this
issue by deregistering UART bus client in error path.

Also correct error path with clock usage.
