platform/x86: thinkpad_acpi: Take hotkey_mutex during hotkey_exit()
[ Upstream commit e397c564298c2e91aea3887990da8e8eddb65277 ]
hotkey_exit() already takes the mutex around the hotkey_poll_stop_sync()
call, but not around the other calls.
commit 38831eaf7d4c ("platform/x86: thinkpad_acpi: use lockdep
annotations") has added lockdep_assert_held() checks to various hotkey
functions.
These lockdep_assert_held() checks fail causing WARN() backtraces in
dmesg due to missing locking in hotkey_exit(), fix this.
Fixes: 38831eaf7d4c ("platform/x86: thinkpad_acpi: use lockdep annotations")
