ext4: move setting of trimmed bit into ext4_try_to_trim_range()

[ Upstream commit 45e4ab320c9b5fa67b1fc3b6a9b381cfcc0c8488 ]

Currently we set the group's trimmed bit in ext4_trim_all_free() based
on return value of ext4_try_to_trim_range(). However when we will want
to abort trimming because of suspend attempt, we want to return success
from ext4_try_to_trim_range() but not set the trimmed bit. Instead
implementing awkward propagation of this information, just move setting
of trimmed bit into ext4_try_to_trim_range() when the whole group is
trimmed.
