qcacmn: Fix compiler warning on shift overflow in QCA vendor definitions

Fx the following compiler error:
qca-vendor.h:5892:54: error: result of ‘1 << 31’ requires 33 bits to represent, but ‘int’ only has 32 bits [-Werror=shift-overflow=]
 5892 |  QCA_WLAN_VENDOR_CHANNEL_PROP_FLAG_HE40INTOL     = 1 << 31,

This "1" needs to be marked unsigned for this case of MSB=1.
