vt_ioctl: Remove in_interrupt() check
reset_vc() uses a "!in_interrupt()" conditional before resetting the palettes, which is a blocking operation. Since commit 8b6312f4dcc1e ("[PATCH] vt: refactor console SAK processing") all calls are invoked from a workqueue process context, with the blocking console lock always acquired. Remove the "!in_interrupt()" check. Signed-off-by: Ahmed S.
