[PATCH v2 1/2] Making si_swapinfo exportable

[Leonid Moiseichuk <leonid.moiseichuk@nokia.com>]

If we will make si_swapinfo() exportable it could be called from modules.
Otherwise modules have no interface to obtain information about swap usage.
Change made in the same way as si_meminfo() declared.
