ext4: using nofail preallocation in ext4_es_insert_extent()

Browse source

[ Upstream commit 2a69c45008 ]

Similar to in ext4_es_insert_delayed_block(), we use preallocations that
do not fail to avoid inconsistencies, but we do not care about es that are
not must be kept, and we return 0 even if such es memory allocation fails.
