CVE-2025-38657

wifi: rtw89: mcc: prevent shift wrapping in rtw89_core_mlsr_switch()

In the Linux kernel, the following vulnerability has been resolved:

wifi: rtw89: mcc: prevent shift wrapping in rtw89_core_mlsr_switch()

The "link_id" value comes from the user via debugfs.  If it's larger
than BITS_PER_LONG then that would result in shift wrapping and
potentially an out of bounds access later.  In fact, we can limit it
to IEEE80211_MLD_MAX_NUM_LINKS (15).

Fortunately, only root can write to debugfs files so the security
impact is minimal.
