qcacld-3.0: Fix compilation with WLAN_FEATURE_ROAM_OFFLOAD disabled

When LFR3 compile time flag WLAN_FEATURE_ROAM_OFFLOAD is
disabled, compilation of wlan driver fails as btk_key is defined
under WLAN_FEATURE_ROAM_OFFLOAD but sme_add_key_btk tries to
access this value irrespective of the compile time flag.

As the caller of sme_add_key_btk, calls this only if the
function hdd_is_btk_enc_type returns true and this function
hdd_is_btk_enc_type() is conditionally compiled based on
WLAN_FEATURE_ROAM_OFFLOAD, its better to include sme_add_key_btk
only if WLAN_FEATURE_ROAM_OFFLOAD is enabled.
