irqchip/ti-sci-inta: Use ERR_CAST inlined function instead of ERR_PTR(PTR_ERR(...))
A coccicheck run provided information like the following.
drivers/irqchip/irq-ti-sci-inta.c:250:9-16: WARNING: ERR_CAST can be used
with vint_desc.
Generated by: scripts/coccinelle/api/err_cast.cocci
Thus adjust the exception handling in one if branch.
