From: Kaitao Cheng <redacted>

A later change will make list_for_each_entry() cache the next element
before entering the loop body. tegra_qspi_non_combined_seq_xfer() can
consume the following transfer as part of the current operation and then
advance the loop cursor to that entry.

Keep the transfer walk open-coded so the loop step observes that cursor
update and skips the consumed transfer. This preserves the existing
message sequencing semantics and prepares the code for the list iterator
update.
