[PATCH 22/28] media: atomisp: Remove snr_mbus_fmt local var from atomisp_try_fmt()

[Hans de Goede <hdegoede@xxxxxxxxxx>]

snr_mbus_fmt is a local variable pointing to a substruct of another local
variable which really just makes the code harder to read / follow,
so drop it.

And likewise also drop the stream_info local variable.
