tty: vt, fix bogus division in csi_J
commit 42acfc6615f47e465731c263bee0c799edb098f2 upstream.
In csi_J(3), the third parameter of scr_memsetw (vc_screenbuf_size) is
divided by 2 inappropriatelly. But scr_memsetw expects size, not
count, because it divides the size by 2 on its own before doing actual
memset-by-words.
So remove the bogus division.
