x86/MSR: Filter MSR writes through X86_IOC_WRMSR_REGS ioctl too
Commit
a7e1f67ed29f ("x86/msr: Filter MSR writes")
introduced a module parameter to disable writing to the MSR device file
and tainted the kernel upon writing. As MSR registers can be written by
the X86_IOC_WRMSR_REGS ioctl too, the same filtering and tainting should
be applied to the ioctl as well.
