scsi: ufs: core: Initialize hba->reserved_slot earlier

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.
