    atm: iphase: Do PCI error checks on own line
    
    [ 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.
