libflashrom.c: Invert if conditions to improve the readability

Invert some if conditions to improve the readability of the code.
Instead of running some code if the specific condition applies, error
out early and reduce the indentation levels.

Also, while at it, move the initializers for these for-loops iterators
into their constructs. They are only used by them.
