drm/amd/display: Remove unnecessary DC FP guard

[Why & How]
For dcn2x_fast_validate_bw(), not only populate_dml_pipes needs FP guard
but also dml_get_voltage_level().

Remove unnecessary DC_FP_START/DC_FP_END guard in dcn20_fast_validate_bw
and dcn21_fast_validate_bw. FP guard is already there before calling
dcn2x_validate_bandwidth_fp().
