of/irq: Fix interrupt-map cell length check in of_irq_parse_imap_parent()
On a malformed interrupt-map property which is shorter than expected by
1 cell, we may read bogus data past the end of the property instead of
returning an error in of_irq_parse_imap_parent().
Decrement the remaining length when skipping over the interrupt parent
phandle cell.
Fixes: 935df1bd40d4 ("of/irq: Factor out parsing of interrupt-map parent phandle+args from of_irq_parse_raw()")
