thunderbolt: Clean up ring interrupt register indexing

nhi_mask_interrupt() and nhi_clear_interrupt() take "ring" as parameter
but in fact it is not an actual ring but a byte offset to the interrupt
register. Make this less confusing and name the paramers what it really
is and calculate the offset where it is actually needed.

In addition ring_interrupt_active() has two variables called "index"
with different meanings, and the second one shadows the first one
open-coding ring_interrupt_index() as well. Drop that and rename the
remaining what they actually hold.

While there, make the mask variable u32 and use BIT() to avoid signed
shifting.

No functional changes intended.
