Subject: Input: synaptics-rmi4 - fix register descriptor subpacket map construction

From: Andrew Duggan <[email protected]>

commit 3e29d6bb6433ebfa4e187b1164b80baf720d58c3 upstream.

The map_offset variable is specific to the register and needs to be reset in the loop. Otherwise, subsequent register's subpacket maps will have their bits set at the wrong index.
