io_uring/tctx: avoid modifying loop variable in io_ring_add_registered_file

Browse source 
Use a separate 'idx' variable to store the result of array_index_nospec()
instead of modifying the loop variable 'offset' directly. This improves
code clarity by separating the logical index from the sanitized index
used for array access.

No functional change intended.
