[PATCH 2/2] scsi: ufs: Remove the ufshcd_hba_exit() call from ufshcd_async_scan()

[Bart Van Assche <bvanassche@acm.org>]

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.
