fix harmless-by-chance typo in priority inheritance mutex code

commit 54ca677983d47529bab8752315ac1a2b49888870 inadvertently
introduced bitwise and where logical and was intended. since the
right-hand operand is always 0 or -1 whenever the left-hand operand is
nonzero, the behavior happened to be equivalent.
