PCI: Adjust confusing if indentation in pcie_get_readrq 

Author: Julia Lawall <julia@diku.dk>

Indent the branch of an if.

The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)

// 
@r disable braces4@
position p1,p2;
statement S1,S2;
@@

(
if (...) { ... }
|
if (...) S1@p1 S2@p2
)

@script:python@
p1 << r.p1;
p2 << r.p2;
@@

if (p1[0].column == p2[0].column):
  cocci.print_main("branch",p1)
  cocci.print_secs("after",p2)
//
