Revert b68680e4 to make way for the next
patch: "Add 64-bit capability support to the kernel".

We want to keep the vfs_cap_data.data[] structure, using two 'data's for
64-bit caps (and later three for 96-bit caps), whereas
b68680e4 had gotten rid of the 'data' struct
made its members inline.

The 64-bit caps patch keeps the stack abuse fix at get_file_caps(), which was
the more important part of that patch.
