splice: reinstate SIGPIPE/EPIPE handling
commit 52bce91165e5f2db422b2b972e83d389e5e4725c upstream.
Commit 8924feff66f3 ("splice: lift pipe_lock out of splice_to_pipe()")
caused a regression when there were no more readers left on a pipe that
was being spliced into: rather than the expected SIGPIPE and -EPIPE
return value, the writer would end up waiting forever for space to free
up (which obviously was not going to happen with no readers around).
Fixes: 8924feff66f3 ("splice: lift pipe_lock out of splice_to_pipe()")
