[PATCH] tty/vt: Add console_lock check to vt_console_print()

I'm scratching my head why we have this printing_lock. Digging through historical git trees shows that: - Added in 1.1.73, and I found absolutely no reason why. - Converted to atomic bitops in 2.1.125pre2, I guess as part of SMP enabling/bugfixes. - Converted to a proper spinlock in b0940003f25d

I'm scratching my head why we have this printing_lock. Digging through historical git trees shows that: - Added in 1.1.73, and I found absolutely no reason why. - Converted to atomic bitops in 2.1.125pre2, I guess as part of SMP enabling/bugfixes. - Converted to a proper spinlock in b0940003f25d
