Subject: [PATCH 1/4] scsi: ufs: ufs-qcom: Drop unnecessary NULL checks

This code path is only called through one function, and the hba
struct is already accessed in ufshcd_vops_dbg_register_dump() prior to
calling so there is no way for it to be NULL.

Likewise, the print_fn callback is always supplied within this driver
and is always provided.
