qcacld-3.0: Update capability info in Reassoc request to be in sync with BSS

Browse Source 
qcacld-2.0 to qcacld-3.0 propagation

Check if the spectrum management, short preamble, immediate block ack
are supported by BSS before sending Reassoc request in roaming and
reset the corresponding capability info bits in Reassoc request if the
respective BSS does not support it
