drm/amd/display: drop redundant memset() in get_available_dsc_slices()
get_available_dsc_slices() returns the number of indices set, and all of
the users of get_available_dsc_slices() don't cross the returned bound
when iterating over available_slices[]. So, the memset() in
get_available_dsc_slices() is redundant and can be dropped.
Fixes: 97bda0322b8a ("drm/amd/display: Add DSC support for Navi (v2)")
