Subject: [PATCH] staging: rtl8188eu: don't duplicate ieee80211 WLAN_EID_* constants

linux/ieee80211.h already defines constants for information element IDs.
Include it where needed, resolve discrepancies in naming, and remove the
duplicated definitions.

While at it, wrap a line that was too long and remove extra parentheses
in an expression that mixes only equality and logical operators.

Signed-off-by: Jakub Sitnicki <jsitnicki@...il.com>

This patch depends on commit 04fbf979b39b ("rtl8188eu: don't duplicate
ieee80211 constants for status/reason") in staging-next branch.
