Input: rmi4 - fix limit in rmi_register_desc_has_subpacket()

Browse Source 
rmi_register_desc_has_subpacket() should use RMI_REG_DESC_SUBPACKET_BITS,
not RMI_REG_DESC_PRESENCE_BITS, as the limit for subpacket_map.

Fixes: 2b6a321da9 ("Input: synaptics-rmi4 - add support for Synaptics RMI4 devices")
