Pawandeep OzaandAnup Patel 7a90f41fb9 lib: sbi_irqchip: fix MSI EIID gap and tail allocation logic in register_msi ...

Fix sbi_irqchip_register_msi() that prevented contiguous EIID allocation:

- Gap check condition was inverted: the original `h->first_hwirq -
  hwirq < num_hwirq` incorrectly set `found = true` when the gap was
  too small to fit num_hwirq entries. Correct to `>= num_hwirq` so
  allocation only proceeds when sufficient space exists between
  registered handlers.

- Tail-space check `!found && !hwirq` never triggered after iteration
  Replace with `(chip->num_hwirq - hwirq) >= num_hwirq` to correctly
  allocate if handler list is empty.

Fixes: 79e63bc834 ("irqchip: add sbi_irqchip_register_msi support")
