drivers: wifi: nxp: Fix TWT setup issue.

When try to set twt, system will try to
get interface status firstly.
In shim driver, miss filling twt_capable field.
The twt_capable is set as false by default.
Failed to set twt because of incorrect
twt_capable.

Add enhance code to fill twt_capable field
in shim driver.
