qcacld-3.0: Remove hif_exec from NAPI switch

When NAPI is disabled, there are some failures show that certain APIs
are not defined, these APIs are not NAPI related and defined in
hif_exec.c. But this file will not be compiled when CONFIG_WLAN_NAPI
is not defined. Remove this build constraint and encap the NAPI related
APIs with CONFIG_WLAN_NAPI in file hif_exec.c. Meanwhile add the HIF_CE_DIR
for USB and SDIO case, otherwise it has build error after hif_exe.c move to
the common directory.
