scsi: ufs: core: Remove the ufshcd_hba_exit() call from ufshcd_async_scan()
[ Upstream commit ee36710912b2075c417100a8acc642c9c6496501 ]
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.
