fbdev: imsttfb: fix a resource leak in probe

[ Upstream commit aba6ab57a910ad4b940c2024d15f2cdbf5b7f76b ]

I've re-written the error handling but the bug is that if init_imstt()
fails we need to call iounmap(par->cmap_regs).

Fixes: c75f5a550610 ("fbdev: imsttfb: Fix use after free bug in imsttfb_probe")
