Commit b802c8410ca9 ("async_tx: deprecate broken support for channel
switching") in 2017 intended to "prevent async_tx from using an offload
engine if the channel switching capability is enabled" by adding a
suitable ifdef on the corresponding config.
The config for determining if the channel switching capability is
enabled is called CONFIG_ASYNC_TX_ENABLE_CHANNEL_SWITCH, however
the ifdef falsely refers to CONFIG_ASYNC_TX_CHANNEL_SWITCH (note the
missing "ENABLE").
Correct the name of the config to the intended one.
Fixes: b802c8410ca9 ("async_tx: deprecate broken support for channel switching")
