wlan: Remove CSR dot11f IE RSN max len

Max len of CSR_DOT11F_IE_RSN is 114 which is les than the
DOT11F_IE_RSN_MAX_LEN (130) which may result in array overflow
while parsing cckm ie.
TO address this replace CSR_DOT11F_IE_RSN_MAX_LEN to with
DOT11F_IE_RSN_MAX_LEN and remove CSR_DOT11F_IE_RSN_MAX_LEN
as it is not getting used anywhere else.
