[igt-dev] [PATCH i-g-t] tests/kms_fbcon_fbt: Do a full connector probe.

kms_fbtcon_fbt appears to fail when it is the first test that is executed
after module load.
'Test requirement not met in function set_mode_for_one_screen, file
../tests/kms_fbcon_fbt.c:153:
Test requirement: i < drm->res->count_connectors'
The problem seems to be that the 1920x1080 bios fb is re-used and that
prunes the 4k mode before test execution. Later, when the test does not
do a full-probe, the eDP connector does not have any valid modes.

<7>[ 12.444411] [drm:drm_mode_debug_printmodeline] Modeline
191:"3840x2160" 60 533250 3840 3888 3920 4000 2160 2163 2168 2222 0x48
0xa
<7>[ 12.444418] [drm:drm_mode_prune_invalid] Not using 3840x2160 mode:
VIRTUAL_X

Fix this by calling drmModeGetConnector() instead
drmModeGetConnectorCurrent()

Note that that test is still expected to fail as PSR status checks are
broken.
