esas2r_probe() calls scsi_host_put() in an error path. However,
esas2r_log_dev() may hit a potential NULL dereference. So use NUll instead.

Wouldn't it be better to move the scsi_host_put() call after the error

There is already a message before the scsi_host_put() call. It is used to record calling function.
