qcacld-3.0: Properly export QCA_COMPUTE_TX_DELAY APIs

Currently the qcacld-3.0 driver does not build cleanly when compiled
with the gcc -Wmissing-prototypes switch. One set of warnings is due
to the QCA_COMPUTE_TX_DELAY APIs not being exported properly.  Address
the warnings by properly exporting these functions.
