staging: comedi: ni_tio: remove BUG() checks for ni_tio_get_gate_src()

Browse source

This function calls some helper functions to convert the counter variant
specific gate select bits into the generic enum ni_gpct_clock_source_bits
equivelent. These helper functions currently BUG() if the gate select
bits are invalid.

This should never happen but refactor the code to return -EINVAL instead
and remove the BUG() checks.
