frecon: keep on trying opening DRM device until frecon has master
display_boot_message script kills existing instance of frecon, which
should allow a new instance of frecon to get DRM master for DRM file it
opens. Except, somehow drm_release associated with the old instance of
frecon gets delayed in kernel for few seconds and the new frecon does
not get master.
This CL adds a loop in frecon that will keep opening the device until it
has master.
BUG=chromium:589122
TEST=boot Chrome OS in normal mode. Edit chromeos_startup and\
chromeos-boot-alert to force block_devmode screen at startup and boot again.
