atm: iphase: Do PCI error checks on own line

Browse Source 
[ Upstream commit c28742447ca9879b52fbaf022ad844f0ffcd749c ]

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 functional changes intended.
