Subject: [PATCH] staging: wlan-ng: resolve sparse endianness error.

Adding le16_to_cpu conversion in prism2sta.c, to resolve outstanding
sparse errors as noted in the current TODO in staging-next. Original
error:

  CHECK   drivers/staging//wlan-ng/prism2usb.c
drivers/staging//wlan-ng/prism2sta.c:1450:29: warning: incorrect type in assignment (different base types)
drivers/staging//wlan-ng/prism2sta.c:1450:29:    expected unsigned short [unsigned] [usertype] link_status_new
drivers/staging//wlan-ng/prism2sta.c:1450:29:    got restricted __le16 [usertype] linkstatus

Sparse error no longer present after change.
