iwlwifi: mvm: fix the keyidx assignment
Fixes an issue that smatch pointed out:
1118
1119 key_flags = cpu_to_le16(keyconf->keyidx & STA_KEY_FLG_KEYID_MSK);
^^^^^^^^^^^^^^^
This is s8.
^^^^^^^^^^^^^^^^^^^^^
STA_KEY_FLG_KEYID_MSK is 0x300.
The result after the bitwise AND is always zero because 0xff & 0x300.
