net: chelsio: cxgb3: check the return value of pci_find_capability()



[ Upstream commit 767b9825ed1765894e569a3d698749d40d83762a ]

The function pci_find_capability() in t3_prep_adapter() can fail, so its
return value should be checked.

Fixes: 4d22de3e ("Add support for the latest 1G/10G Chelsio adapter, T3")
