dell-laptop: Fix allocating & freeing SMI buffer page
[ Upstream commit b8830a4e71b15d0364ac8e6c55301eea73f211da ]
This commit fix kernel crash when probing for rfkill devices in dell-laptop
driver failed. Function free_page() was incorrectly used on struct page *
instead of virtual address of SMI buffer.
This commit also simplify allocating page for SMI buffer by using
__get_free_page() function instead of sequential call of functions
alloc_page() and page_address().
