libkmod: fix return error when opening index
...
When calling kmod_load_resources() we could end up getting a bogus
return value -ENOMEM due to several other reasons, like the index not
existing. Change index_mm_open() to propagate the failure reason so we
can take actions on it or return to the caller.

It has changed in the past, and these days, anyone can get a copy of the

libkmod: dump index files

Provide a function to dump the index files to a certain fd. It could be
more optimized (particularly the functions to dump the index that were
copied and pasted from m-i-t), but it seems like the only user of it is
'modprobe -c', used for debugging purposes. So, keep it as is.

For mmap mode, we can avoid allocating and copying strings from the
mmap'ed memory.
With that we have fixed length "struct index_mm_value" that can be
allocated inline with "struct index_mm_node".

uint32_t reads must be aligned, they're not then use memcpy().
read_alloc_chars_mm() and read_chars_mm() were wrong, normalize all
address calculation using single byte pointer "addr" that is
incremented by the amount read, this will avoid further errors.
