[ Upstream commit fc89cc358fb64e2429aeae0f37906126636507ec ]

Release resources when attaching to ULD fail. Otherwise, data
mismatch is seen between LLD and ULD later on, which lead to
kernel panic when accessing resources that should not even
exist in the first place.

Fixes: 94cdb8bb ("cxgb4: Add support for dynamic allocation of resources for ULD")
