[PATCH 1/2] Bluetooth: btmtksdio: Remove redundant firmware filename override

btmtksdio_setup() derives the firmware filename with
btmtk_fw_get_filename() and then overwrites it with an snprintf() that
open-codes that helper's fallback format. Commit 7f935b21bee4 ("Bluetooth:
btmtk: apply the common btmtk_fw_get_filename") added the helper call
without removing the snprintf() it was meant to replace.

None of the device ids the helper special-cases can appear here: 0x6639,
0x7925 and the flavored 0x7961 belong to parts with no SDIO interface, and
btmtksdio_setup() passes a flavor of 0 accordingly. The helper always falls
through to the snprintf()'s own format, so both produce the same string and
removing it is a no-op.

Remove it anyway, since it silently defeats the helper for any device id
the helper special-cases.
