Denis Kirjanov cb2d3883c6 powerpc/msi: Free the bitmap if it was slab allocated ...

During the MSI bitmap test on boot kmemleak spews the following trace:

unreferenced object 0xc00000016e86c900 (size 64):
    comm "swapper/0", pid 1, jiffies 4294893173 (age 518.024s)

Add a flag to msi_bitmap for tracking allocations from slab and memblock
so we can properly free/handle memory in msi_bitmap_free().
