x86: initialize io_bitmap_base on 32bit

commit 14edda2f863e827c27c2b8fcf879d8b7facbde11 (x86-32: use non-lazy
io bitmap context switching) broke ioperm for 32bit because it removed
the lazy initialization of io_bitmap_base and did not set it to the
real bitmap offset.

[ Impact: fix non-working sys_ioperm() on 32-bit kernels ]
