viafb: Fix various resource leaks during module_init()

Browse source

The current code executed from module_init() in viafb does not have
proper error checking and [partial] resoure release paths in case
an error happens half way through driver initialization.

This patch adresses the most obvious of those issues, such as a
leftover i2c bus if module_init (and thus module load) fails.

[jc: fixed merge conflicts]
[jc: also restored -ENOMEM return on ioremap() fail]
