Fix protocol error (#1106)

Fix ProtocolError

This commit attempts to fix hiredis such that a recoverable write error
will be retried rather than throwing a hard error.

Since our read/write functions are now behind function pointers, we
specify semantically that a return value of < 0 is a hard error, 0 a
recoverable error, and > 0 a success.

Our default `redisNetRead` function was already doing something similar
so this also improves code consistency.

Resolves #961
