[PATCHv3] ath10k: fix boot failure in UTF mode/testmode

[c_traja]

From: Tamizh chelvam <c_traja@qti.qualcomm.com>

Rx filter reset and the dynamic tx switch mode (EXT_RESOURCE_CFG)
configuration are causing the following errors when UTF firmware
is loaded to the target.

Error message 1:
[ 598.015629] ath10k_pci 0001:01:00.0: failed to ping firmware: -110
[ 598.020828] ath10k_pci 0001:01:00.0: failed to reset rx filter: -110
[ 598.141556] ath10k_pci 0001:01:00.0: failed to start core (testmode): -110

Error message 2:
[ 668.615839] ath10k_ahb a000000.wifi: failed to send ext resource cfg command : -95
[ 668.618902] ath10k_ahb a000000.wifi: failed to start core (testmode): -95

Avoiding these configurations while bringing the target in
testmode is solving the problem.
