[PATCH] rtlwifi: rtl8821ae: add in a missing break in switch statement

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

The switch case RATR_INX_WIRELESS_MC has a missing break, this seems
to be unintentional as the setting of variable ret gets overwritten
when the case falls through to the following RATR_INX_WIRELESS_AC_5N
case.  Fix this by adding in the missing break.

Detected by CoverityScan, CID#1167237 ("Missing break in switch")

Fixes: 3c05bedb5fef ("Staging: rtl8812ae: Add Realtek 8821 PCI WIFI driver")
