qlcnic: clean up qlcnic_init_pci_info()
In the original code we allocated memory conditionally and freed it in the error handling unconditionally. It turns out that this function is only called during initialization and "adapter->npars" and "adapter->eswitch" are always NULL at the start of the function. I removed those checks. Also since I was cleaning things, I changed the error handling for qlcnic_get_pci_info() and pulled everything in an indent level.
