[PATCH] pipe: remove CONFIG_WATCH_QUEUE for several protoypes

[Ben Dooks]

There are several function protoypes in include/linux/pipe_fs_i.h which
are only declared for CONFIG_WATCH_QUEUE. However these seem to be used
even if this is not declared, and their implementations in fs/pipe.c are
not conditional on CONFIG_WATCH_QUEUE. Silence the following sparse warnings
by alwas defining these:

fs/pipe.c:759:15: warning: symbol 'account_pipe_buffers' was not declared. Should it be static?
fs/pipe.c:765:6: warning: symbol 'too_many_pipe_buffers_soft' was not declared. Should it be static?
fs/pipe.c:772:6: warning: symbol 'too_many_pipe_buffers_hard' was not declared. Should it be static?
fs/pipe.c:779:6: warning: symbol 'pipe_is_unprivileged_user' was not declared. Should it be static?
