wifi: ath11k: fix WCN6750 firmware crash caused by 17 num_vdevs

BugLink: https://bugs.launchpad.net/bugs/2074091

[ Upstream commit ed281c6ab6eb8a914f06c74dfeaebde15b34a3f4 ]

WCN6750 firmware crashes because of num_vdevs changed from 4 to 17
in ath11k_init_wmi_config_qca6390() as the ab->hw_params.num_vdevs
is 17. This is caused by commit f019f4dff2e4 ("wifi: ath11k: support
2 station interfaces") which assigns ab->hw_params.num_vdevs directly
to config->num_vdevs in ath11k_init_wmi_config_qca6390(), therefore
WCN6750 firmware crashes as it can't support such a big num_vdevs.

Fix it by assign 3 to num_vdevs in hw_params for WCN6750 as 3 is
sufficient too.

Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3
Tested-on: WCN6750 hw1.0 AHB WLAN.MSL.1.0.1-01371-QCAMSLSWPLZ-1
