The req to be async cancelled will most likely return -ECANCELED after
cancellation with the new async bybrid optimization applied. And -EINTR
is impossible to be returned anymore since we won't be in INTERRUPTABLE
sleep when reading, so remove it.

ping this one since test/io-cancel will be broken
if the async hybrid logic merges to 5.16
