scsi: ufs: ufs-mediatek: Fix build warnings with make W=1

Fix build warnings with make W=1 as below,

1.
>> drivers/scsi/ufs/ufs-mediatek.c:116:22: warning: format '%d' expects
>> argument of type 'int', but argument 4 has type 'long int'

2.
  CC [M]  drivers/scsi/ufs/ufs-mediatek.o
../drivers/scsi/ufs/ufs-mediatek.c:749: error: Cannot parse struct or union!

/** is used specifically with kernel-doc tool.
As a quick fix by removing dubious /** in the comment block of
struct ufs_hba_variant_ops ufs_hba_mtk_vops.
