[PATCH] fs/direct-io.c: include fs/internal.h for sb_init_dio_done_wq()

[PATCH] fs/direct-io.c: include fs/internal.h for sb_init_dio_done_wq()

[Eric Biggers]

From: Eric Biggers <ebiggers@google.com>

sb_init_dio_done_wq() is defined in fs/direct-io.c and declared in
fs/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.
