f2fs: set pin_file under CAP_SYS_ADMIN (2019-03-14 10:20:54 -0700)

----------------------------------------------------------------
f2fs-for-5.1-rc1

We've continued mainly to fix bugs in this round, as f2fs has been shipped
in more devices. Especially, we've focused on stabilizing checkpoint=disable
feature, and provided some interfaces for QA.

Enhancement:
- expose FS_NOCOW_FL for pin_file
- run discard jobs at unmount time with timeout
- tune discarding thread to avoid idling which consumes power
- some checking codes to address vulnerabilities
- give random value to i_generation
- shutdown with more flags for QA

Bug fix:
- clean up stale objects when mount is failed along with checkpoint=disable
- fix system being stuck due to wrong count by atomic writes
- handle some corrupted disk cases
- fix a deadlock in f2fs_read_inline_dir

We've also added some minor build errors and clean-up patches.
