kconfig: fix line number in recursive inclusion error message
When recursive inclusion is detected, the line number of the last
'included from:' is wrong.
[Test Case]
Kconfig:
-------->8--------
source "Kconfig2"
-------->8--------
Kconfig2:
-------->8--------
source "Kconfig3"
-------->8--------
Kconfig3:
-------->8--------
source "Kconfig"
-------->8--------
[Result]
$ make allyesconfig
scripts/kconfig/conf --allyesconfig Kconfig
Kconfig:1: recursive inclusion detected. Inclusion path:
current file : 'Kconfig'
included from: 'Kconfig3:1'
included from: 'Kconfig2:1'
included from: 'Kconfig:3'
scripts/kconfig/Makefile:89: recipe for target 'allyesconfig' failed
make[1]: *** [allyesconfig] Error 1
Makefile:512: recipe for target 'allyesconfig' failed
make: *** [allyesconfig] Error 2
where we expect
current file : 'Kconfig'
included from: 'Kconfig3:1'
included from: 'Kconfig2:1'
included from: 'Kconfig:1'
The 'iter->lineno+1' in the second fpinrtf() should be 'iter->lineno-1'.
I refactored the code to merge the two fprintf() calls.
