name_to_int() is defined in fs/proc/util.c and declared in
fs/proc/internal.h, but the declaration isn't included at the point of
the definition. Include the header to enforce that the definition
matches the declaration.
This addresses a gcc warning when -Wmissing-prototypes is enabled.

Gcc doesn't know that "len" is guaranteed to be >=1 by dcache and
generates standard while-loop prologue duplicating loop condition.
