Move the hba->reserved_slot and the host->can_queue assignments from
ufshcd_config_mcq() into ufshcd_alloc_mcq(). The advantages of this
change are as follows:
- It becomes easier to verify that these two parameters are updated
  if hba->nutrs is updated.
- It prevents unnecessary assignments to these two parameters. While
  ufshcd_config_mcq() is called during host reset, ufshcd_alloc_mcq()
  is not.
