[PATCH for-4.2] hw/i386: Fix compiler warning when CONFIG_IDE_ISA is disabled

[Thomas Huth <thuth@redhat.com>]

When CONFIG_IDE_ISA is disabled, compilation currently fails:

 hw/i386/pc_piix.c: In function ‘pc_init1’:
 hw/i386/pc_piix.c:81:9: error: unused variable ‘i’ [-Werror=unused-variable]

Move the variable declaration to the right code block to avoid
this problem.

Fixes: 4501d317b50e ("hw/i386/pc: Extract pc_i8259_create()")
