power: supply: cpcap-charger: Fix null check for power_supply_get_by_name
In the cpcap_usb_detect() function, the power_supply_get_by_name()
function may return `NULL` instead of an error pointer.
To prevent potential null pointer dereferences, Added a null check.
Fixes: eab4e6d953c1 ("power: supply: cpcap-charger: get the battery inserted infomation from cpcap-battery")
