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.
