qlcnic: clean up qlcnic_init_pci_info()

Browse Source 
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.
