percpu: improve first chunk initial area map handling
Impact: no functional change When the first chunk is created, its initial area map is not allocated because kmalloc isn't online yet. The map is allocated and initialized on the first allocation request on the chunk. This works fine but the scattering of initialization logic between the init function and allocation path is a bit confusing. This patch makes the first chunk initialize and use minimal statically allocated map from pcpu_setpu_first_chunk(). The map resizing path still needs to handle this specially but it's more straight-forward and gives more latitude to the init path. This will ease future changes.
