Revert "qcacld-3.0: fix ipa mcc tx_desc pool size"

This reverts commit I3216a4c14ac624cc313d11226909efd4f63841d0

When alloccate free Tx desc list, Tx desc pool size is not initialized yet,
so tx_desc_size is set to 0.
This cause free Tx descriptor allocation failed.

* gIPAMccTxDescSize - hdd_ipa_tx_desc pool size for MCC TX
* @Min: 512
* @Max: 4096
* @Default: 1024
*
* This ini is used to specify hdd_ipa_tx_desc pool size for MCC TX path.
* The pool is maintained to have a one-to-one mapping with desc from IPA
* driver so that when wlan TX completes, wlan driver could replenish the
* correct desc to IPA driver. Note that in MCC TX case, desc size is limited
* to global tx desc pool size. Therefore the real hdd_ipa_tx_desc pool size
* is the minimum of this ini and global tx desc pool size.
