qcom: smb-lib: rerun APSD on insertion for micro USB mode 



In case of very slow insertion of SDP/DCP there is a possibility
that D+/D- makes contact while APSD is in progress. This will
result in an incorrect type detection.
Fix this by doing a APSD rerun after charger-type detection is
complete.
