[PATCH] uefi: uefirtvariable: explicitly ignore ioctl() return

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

The code is deliberately ignoring the return from ioctl() but
Coverity Scan is complaining about this.  Explicitly use (void)
casts to indicate that we're really not interested in the ioctl
return.
