[PATCH] liquidio CN23XX: check if PENDING bit is clear using logical and

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

the mbox state should be bitwise anded rather than logically anded
with OCTEON_MBOX_STATE_RESPONSE_PENDING. Fix this by using the
correct & operator instead of &&.
