regmap: regmap-irq: fix getting type default values 

Checking for value of type default value just after allocating will
always be zero and the type register default values will never be read,
so fix this!

Without this patch setting irq type will be silently ignored.
Patch "regmap: regmap-irq: Remove default irq type setting from core"
did remove the default mask but it forgot to remove the check before
reading the default type register.
