wpa_supplicant: Fix wpa_supplicant configuration parsing error

[Michael-CY Lee]

From: Michael Lee <michael-cy.lee at mediatek.com>

In the original flow, after hostapd_config_tx_queue successfully
parses a tx_queue variable, it would not return immediately. Then it
would print out "unknow global field" later and set return val to -1.

This patch returns immediately after hostapd_config_tx_queue
successfully parses a tx_queue variable.
