[media] media: Init the reserved fields of struct media_link_desc

struct media_link_desc is copy_to_user'ed as the return value of
MEDIA_IOC_ENUM_LINKS. When copying, the driver is omitting to initialise
the reserved fields.  This commit fixes that by initialising the
reserved fields to 0.

Undo stable backports

This is a squash of a bunch of stable backport patches that we
shouldn't be holding onto in msm-3.4 because they only apply to
kernels before v3.4.
