[PATCH 06/14] irqchip: crossbar: fix memory leak incase of invalid entry

[Sricharan R]

From: Nishanth Menon <nm at ti.com>

When the provided unused skip list entry is greater than max irqs
possible, we go to err3, but we fail to free register_offsets,
should have returned to err4 instead which ensures that allocated
register_offsets are freed as well.
