The function transport_register_device() can return error code.
However, scsi_sysfs_add_host() currently does not check return value
of transport_register_device() and always returns 0.
Also, return value of scsi_sysfs_add_host() is
checked at drivers/scsi/hosts.c:307.

Therefore, this commit adds error checking for transport_register_device()
and returning error code in scsi_sysfs_add_host().
