fbdev: imsttfb: fix a resource leak in probe

In the Linux kernel, the following vulnerability has been resolved:

fbdev: imsttfb: fix a resource leak in probe

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

CWE-416 Use After Free

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
