Benjamin Herrenschmidt d16136d22a cirrus: Fix host CPU blits 
Commit b2eb849d4b
"CVE-2007-1320 - Cirrus LGD-54XX "bitblt" heap overflow" broke
cpu to video blits.

When the ROP function is called from cirrus_bitblt_cputovideo_next(),
we pass 0 for the pitch but only operate on one line at a time. The
added test was tripping because after the initial substraction, the
pitch becomes negative. Make the test only trip when the height is
larger than one (ie. the pitch is actually used).

This fixes HW cursor support in Windows NT4.0 (which otherwise was
a white rectangle) and general display of icons in that OS when using
8bpp mode.
