regulator: max14577: Add error check for max14577_read_reg()

Browse source

commit 65271f868c upstream.

The function max14577_reg_get_current_limit() calls the function
max14577_read_reg(), but does not check its return value. A proper
implementation can be found in max14577_get_online().

Add a error check for the max14577_read_reg() and return error code
if the function fails.
