rtlwifi: Fix static checker warnings for various drivers

Indenting errors yielded the following static checker warnings:

drivers/net/wireless/rtlwifi/rtl8192ee/hw.c:533 rtl92ee_set_hw_reg() warn: add curly braces? (if)
drivers/net/wireless/rtlwifi/rtl8192ee/hw.c:539 rtl92ee_set_hw_reg() warn: add curly braces? (if)

An unreleased version of the static checker also reported:

drivers/net/wireless/rtlwifi/rtl8723be/trx.c:550 rtl8723be_rx_query_desc() warn: 'hdr' can't be NULL.
drivers/net/wireless/rtlwifi/rtl8188ee/trx.c:621 rtl88ee_rx_query_desc() warn: 'hdr' can't be NULL.
drivers/net/wireless/rtlwifi/rtl8192ee/trx.c:567 rtl92ee_rx_query_desc() warn: 'hdr' can't be NULL.
drivers/net/wireless/rtlwifi/rtl8821ae/trx.c:758 rtl8821ae_rx_query_desc() warn: 'hdr' can't be NULL.
drivers/net/wireless/rtlwifi/rtl8723ae/trx.c:494 rtl8723e_rx_query_desc() warn: 'hdr' can't be NULL.
drivers/net/wireless/rtlwifi/rtl8192se/trx.c:315 rtl92se_rx_query_desc() warn: 'hdr' can't be NULL.
drivers/net/wireless/rtlwifi/rtl8192ce/trx.c:392 rtl92ce_rx_query_desc() warn: 'hdr' can't be NULL.

All of these are fixed.
