[PATCH] staging/goldfish: use 6-arg get_user_pages()

[Arnd Bergmann]

After commit cde70140fed8 ("mm/gup: Overload get_user_pages() functions"),
we get warning for this file, as it calls get_user_pages() with eight
arguments after the change of the calling convention to use only six:

drivers/platform/goldfish/goldfish_pipe.c: In function 'goldfish_pipe_read_write':
drivers/platform/goldfish/goldfish_pipe.c:312:3: error: 'get_user_pages8' is deprecated [-Werror=deprecated-declarations]

This removes the first two arguments, which are now the default.

The API change is currently only in the mm/pkeys branch of the
tip tree, while the goldfish_pipe driver started using the
old API in the staging/next branch.

Andrew could pick it up into linux-mm in the meantime, or I can
resend it at some later point if nobody else does the change
after 4.6-rc1.
