FROMLIST: scsi: ufs: Remove the ufshcd_hba_exit() call from ufshcd_async_scan()

Browse Source 
Calling ufshcd_hba_exit() from a function that is called asynchronously
from ufshcd_init() is wrong because this triggers multiple race
conditions. Instead of calling ufshcd_hba_exit(), log an error message.
