[patch 1/2] qlcnic: clean up qlcnic_init_pci_info()

[Dan Carpenter <error27@gmail.com>]

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.
