[igt-dev] [PATCH i-g-t] igt/gem_exec_params: Drop drm master privileges only on drm master fds

[Antonio Argenziano]

Subtest 'secure-non-master' tries to drop drm-master privileges on a
non drm-master fd. Instead drop master privileges after the subtest
acquires it so that other subtests are not affected by it.
