staging: sm750fb: Call iounmap() to free mapped bus memory
If ioremap_wc() fails, the code jumps to the "exit" label and forgets to
free the bus memory mapped into "sm750_dev->pvReg". Mapped bus memory must
always be freed by calling iounmap().
Call iounmap(sm750_dev->pvReg) when the above-mentioned failures happen.
The site of the missing iounmap() has been detected by Smatch.
