What does this PR do?

During the mount of a device a call to blkid is done, to get
information of the current devices.

blkid is a slow operation, to avoid that use an internal cache,
that is specified in /etc/blkid configuration file, but a single
blkid can still redo this cache file, making the second call
equally slow.

This patch cache the blkid information for _active_mountinfo in
the context dict, making the next mount action a fast
operation.

Tests written?

No, as this patch do not change the mount behavior, only makes
the second call faster.
