f2fs: remove clear SB_INLINECRYPT flag in default_options

In the Linux kernel, the following vulnerability has been resolved:

f2fs: remove clear SB_INLINECRYPT flag in default_options

In f2fs_remount, SB_INLINECRYPT flag will be clear and re-set.
If create new file or open file during this gap, these files
will not use inlinecrypt. Worse case, it may lead to data
corruption if wrappedkey_v0 is enable.

Thread A:                               Thread B:

-f2fs_remount				-f2fs_file_open or f2fs_new_inode
  -default_options
	<- clear SB_INLINECRYPT flag

                                          -fscrypt_select_encryption_impl

  -parse_options
	<- set SB_INLINECRYPT again
