[PATCH v9 2/6] Bluetooth: btmtksdio: Remove redundant firmware filename override

[Chris Lu <chris.lu@mediatek.com>]

btmtksdio_setup() calls btmtk_fw_get_filename() to generate the correct
firmware filename based on chip ID, then immediately overwrites it with
snprintf() using a generic legacy format. This causes newer chips that
require chip-specific firmware paths (MT6639, MT7925, MT7928) to request
incorrect legacy filenames, leading to firmware load failures.

The USB driver (btmtkusb.c) correctly uses btmtk_fw_get_filename()
without overriding the result. Match that behavior by removing the
redundant snprintf() call.

Fixes: 7f935b21bee4 ("Bluetooth: btmtk: apply the common btmtk_fw_get_filename")
