Mike Rapoport (Microsoft) cb7907e36c proc: replace __get_free_page() with kmalloc() ...

A few functions in fs/proc/base.c use __get_free_page() to allocate a
temporary buffer.

kmalloc() is a better API for such use and it also provides better
scalability and more debugging possibilities.

Replace use of __get_free_page() with kmalloc().
