vt_ioctl: Remove in_interrupt() check

Browse source 
reset_vc() uses a "!in_interrupt()" conditional before resetting the
palettes, which is a blocking operation. Since commit
   8b6312f4dc ("[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.
