[PATCH v2] staging: wlan-ng: Amend type mismatch warnings

[sunil . m]

From: Suniel Mahesh <sunil.m@xxxxxxxxxxxx>

le16_to_cpu() accepts argument of type __le16 and cpu_to_le16()
returns an argument of type __le16. This patch fixes warnings
related to incorrect type in assignment and changes the types
in the corresponding header file.
The following type mismatch warnings reported by sparse
have been amended:
warning: cast to restricted __le16
warning: incorrect type in assignment (different base types)

Signed-off-by: Suniel Mahesh <sunil.m@xxxxxxxxxxxx>

Changes for v2:
- Reworked on the patch and modified commit message as per the
  recommendations from Frans Klaver and Greg K-H.

- Patch was tested and built on next-20170609 and staging-testing.
