[PATCH] media: av7110: refactor deeply nested PTS loops

[André Moreira]

Extract the deeply nested loops handling PTS flags in the MPEG-1
block into a separate helper function `av7110_ipack_m1_pts()`.

This fixes a checkpatch warning regarding too many leading tabs and
improves code readability without changing the underlying parser logic.
