bcma: add missing iounmap on error path 

This should fix the problem reported by Fengguang:

The coccinelle static checker emits these warnings:

drivers/bcma/scan.c:466:3-9: ERROR: missing iounmap; ioremap on line 451 and execution via conditional on line 465
drivers/bcma/scan.c:540:3-9: ERROR: missing iounmap; ioremap on line 515 and execution via conditional on line 539
