staging: wlan-ng: remove volatile from reapable field in hfa384x_usbctlx
Fix checkpatch.pl warning:
"Use of volatile is usually wrong: see
Documentation/process/volatile-considered-harmful.rs"
reapable is not used to access h/w directly, so volatile is not
necessary.
>From reading the code, the contexts in which the field may be
updated/accessed across threads are protected by the hw->ctlxq.lock
spinlock, where hw is the device struct, so appears thread-safe.
