internal.c: Pass `programmer_cfg` to `try_mtd()`

Programmer params are now passed via the `programmer_cfg` struct, but
the internal programmer did not pass them to the `try_mtd()` function
which was still using `NULL`. This problem resulted in a segmentation
fault when trying to use the internal programmer.

TEST=Make sure internal programmer does not segfault on Haswell ULT.
