Usb: Add status check to prevent NPE
This patch prevents a Null Pointer Exception in
queryMoistureDetectionStatus() when getPortStatusHelper() fails to open
the /sys/class/typec file. The failure results in an empty
currentPortStatus vector, causing the NPE when accessing its first
element.
Bug: 361097811
Flag: EXEMPT bugfix
Test: NPE does not occur when getPortStatusHelper() fails
