[PATCH v2 4/8] atm: iphase: Do PCI error checks on own line

["Ilpo Järvinen" <ilpo.jarvinen@linux.intel.com>]

In get_esi() PCI errors are checked inside line-split if conditions (in
addition to the file not following the coding style). To make the code
in get_esi() more readable, fix the coding style and use the usual
error handling pattern with a separate variable.

In addition, initialization of 'error' variable at declaration is not
needed.

No function changes intended.
