Sherry Sun a0835444f1 mxm_wifiex: update to mxm5x17344.p1 release 
Driver Bug Fixes:
-----------------
1. WCSWREL-352: Fixed WiFi driver kernel panic with "use after free" print
2. WCSWREL-353: Fixed WiFi driver panic when switch AP to another AP
3. WCSWREL-337: merge the L5.18 build errors and warnings fix patches into next wifi release
4. WSW-16518: Fixed STA going to unresponsive state during basic UAPSD operation
5. WSW-19350: Observed "unexpected kernel BRK exception" in STA 2G VHT with BT HID traffic running simultaneously
6. WSW-19640: cannot enable the "20/40 BSS Coexistence Management" support
