irqchip/mchp-eic: Fix error code in mchp_eic_domain_alloc()
[ Upstream commit 7dbc0d40d8347bd9de55c904f59ea44bcc8dedb7 ]
If irq_domain_translate_twocell() sets "hwirq" to >= MCHP_EIC_NIRQ (2) then
it results in an out of bounds access.
The code checks for invalid values, but doesn't set the error code. Return
-EINVAL in that case, instead of returning success.
