Subject: [PATCH] unix: fix assert on signal pipe overflow

An incorrect assert() statement was causing libuv to crash when writing
to an internal signal pipe would result in EAGAIN/EWOULDBLOCK.

This commit doesn't solve the underlying issue that the signal pipe can
overflow.

This should fix joyent/node#5538
