Subject: drm/tilcdc: remove unnecessary state->fb check
Git-commit: 26c06633f6b1ed03c2b9bb3484e9777e95f03d31
Patch-mainline: v5.9-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322

tilcdc_plane_atomic_check() exits if state->fb == NULL, so no need to
check it again later.
