[PATCH] bcachefs: Change opts param to const pointer in bch2_opts_to_text

[Riyan Dhiman]

Convert struct bch_opts opts to const struct bch_opts *opts in
bch2_opts_to_text() function paramter. This improves efficiency by
avoiding structure copying and reflects the function's read-only
access to opts.

Fixes: 283ba1b92b1c (bcachefs: bch2_opts_to_text())
