bnxt_en: Free context memory after disabling PCI in probe error path.

[ Upstream commit a3e614dae0dd710749d4963ceb105d566a6c55ac ]

Other shutdown code paths will always disable PCI first to shutdown DMA
before freeing context memory.  Do the same sequence in the error path
of probe to be safe and consistent.
