ocfs2: Wrap signal blocking in void functions.

ocfs2 sometimes needs to block signals around dlm operations, but it
currently does it with sigprocmask().  Even worse, it's checking the
error code of sigprocmask().  The in-kernel sigprocmask() can only error
if you get the SIG_* argument wrong.  We don't.

Wrap the sigprocmask() calls with ocfs2_[un]block_signals().  These
functions are void, but they will BUG() if somehow sigprocmask() returns
an error.
