Sam Ravnborg 161f5a1189 sparc64: Fix number of online CPUs 
commit 98937707fea8375e8acea0aaa0b68a956dd52719 upstream.

Nick Bowler reported:
    When using newer kernels on my Ultra 60 with dual 450MHz UltraSPARC-II
    CPUs, I noticed that only CPU 0 comes up, while older kernels (including
    4.7) are working fine with both CPUs.

      I bisected the failure to this commit:

      9b2f753ec2 is the first bad commit
      commit 9b2f753ec2

      sparc64: Fix cpu_possible_mask if nr_cpus is set

    This is a small change that reverts very easily on top of 5.18: there is
    just one trivial conflict.  Once reverted, both CPUs work again.

    Maybe this is related to the fact that the CPUs on this system are
    numbered CPU0 and CPU2 (there is no CPU1)?

The current code that adjust cpu_possible based on nr_cpu_ids do not
take into account that CPU's may not come one after each other.
Move the chech to the function that setup the cpu_possible mask
so there is no need to adjust it later.
