[PATCH] fs/buffer.c: include fs/internal.h for missing prototypes

[Eric Biggers <ebiggers@kernel.org>]

From: Eric Biggers <ebiggers@google.com>

__block_write_begin_int(), __generic_write_end(), and guard_bio_eod()
are defined in fs/buffer.c and declared in fs/internal.h, but the
declarations aren't included at the point of the definitions.  Include
the header to enforce that the definitions match the declarations.

This addresses gcc warnings when -Wmissing-prototypes is enabled.
