Baokun Li 73a2f03365 ext4: factor out __es_alloc_extent() and __es_free_extent()
Factor out __es_alloc_extent() and __es_free_extent(), which only allocate
and free extent_status in these two helpers.

The ext4_es_alloc_extent() function is split into __es_alloc_extent()
and ext4_es_init_extent(). In __es_alloc_extent() we allocate memory using
GFP_KERNEL | __GFP_NOFAIL | __GFP_ZERO if the memory allocation cannot
fail, otherwise we use GFP_ATOMIC. and the ext4_es_init_extent() is used to
initialize extent_status and update related variables after a successful
allocation.

This is to prepare for the use of pre-allocated extent_status later.
