[PATCH v3] Work with hartid equal to or greater than SBI_HARTMASK_MAX_BITS

[Raj Vishwanathan]

Some platforms use hartid that is equal to greater than SBI_HARTMASK_MAX_BITS,
so we should remove the original check. Instead we check the hart index
against SBI_HARTMASK_MAX_BITS.

Update: Make hart_count > SBI_HARTMASK_MAX_BITS a catastrophic failure. The reviewer suggested continue, immediate failure quickly will localize the issue.
