Bluetooth: hci_qca: move the SoC type check to the right place
commit 0fb410c914eb03c7e9d821e26d03bac0a239e5db upstream.
Commit 3d05fc82237a ("Bluetooth: qca: set power_ctrl_enabled on NULL
returned by gpiod_get_optional()") accidentally changed the prevous
behavior where power control would be disabled without the BT_EN GPIO
only on QCA_WCN6750 and QCA_WCN6855 while also getting the error check
wrong. We should treat every IS_ERR() return value from
devm_gpiod_get_optional() as a reason to bail-out while we should only
set power_ctrl_enabled to false on the two models mentioned above. While
at it: use dev_err_probe() to save a LOC.
