scsi: ufs: core: Free memory allocated for model before reinit

Under the conditions that a device is to be reinitialized within
ufshcd_probe_hba(), the device must first be fully reset.

Resetting the device should include freeing U8 model (member of dev_info)
but does not, and this causes a memory leak.  ufs_put_device_desc() is
responsible for freeing model.
