Hariprasad Shenai 21d11bd6f0 cxgb4: Enhance driver to update FW, when FW is too old
t4_check_fw_version() can return several error codes (-EINVAL, -EBUSY,
-EAGAIN). The present code sets the adapter state to UNINIT only if its
an EFAULT. In all the error cases set the adapter to uninitialized state.

In t4_check_fw_version() if call to t4_get_fw_version() fails, repeat the
operation a few times before returning failure.
