Jaegeuk Kim fd3551098b BACKPORT: f2fs: split initial and dynamic conditions for extent_cache 
Let's allocate the extent_cache tree without dynamic conditions to avoid a
missing condition causing a panic as below.

 # create a file w/ a compressed flag
 # disable the compression
 # panic while updating extent_cache

F2FS-fs (dm-64): Swapfile: last extent is not aligned to section
F2FS-fs (dm-64): Swapfile (3) is not align to section: 1) creat(), 2) ioctl(F2FS_IOC_SET_PIN_FILE), 3) fallocate(2097152 * N)
Adding 124996k swap on ./swap-file.  Priority:0 extents:2 across:17179494468k
