Added vendor hook after sending UFS command to host
   - trace_android_vh_ufs_send_command_post_change
Added vendor hook for abort success case
   - trace_android_vh_ufs_abort_success_ctrl

Added vendor hook for completion response check
 - trace_android_vh_ufs_compl_rsp_check_done
Added vendor hook for vendor specific error handling
 - trace_android_vh_ufs_err_handler
Added vendor hook for err logs printing control
 - trace_android_vh_ufs_err_print_ctrl
Added vendor hook for error checking flow trigger
 - trace_android_vh_ufs_err_check_ctrl
