Christopher Haster 026833214a Removing zeroing of trailing space in attribute buffers 
This was provided as a courtesy to hopefully make custom attributes more
easy to use, however the zeroing turned out to be a bit complicated when
syncing custom attributes across multiple open files.

Implicitly zeroing trailing buffer space is also inconsistent with the
other APIs in the filesystem, such as lfs_file_read, so this commit
removes the behavior.

If you need to handle differently sized custom attributes, you can
either pre-zero the custom attribute buffers, or use lfs_getattr to find
the on-disk size of custom attributes explicitly.
