qcacld-3.0: Add ini support to configure MGMT retry limit

Currently, default MGMT retry limit is 4 which means 4
transmissions are supported for any management frame.
In noisy environment, Chances to get connection failure
are higher with 4 retransmissions.

Fix is to add INI support mgmt_retry_max to make
CFG_MGMT_RETRY_MAX configurable. Default value for
CFG_MGMT_RETRY_MAX is 15 to reduce the chances of connection
failure in noisy environment.
