wrong memory access in i2o_block_device_lock()

This patch fixes access to memory that has not been allocated:
i2o_msg_get_wait() can returns errors different from I2O_QUEUE_EMPTY.  But the
result is checked only against this code.  If it is not I2O_QUEUE_EMPTY then
we dereference the error code as the pointer later.
