    f2fs: remove clear SB_INLINECRYPT flag in default_options
    
    [ Upstream commit ac5eecf481c29942eb9a862e758c0c8b68090c33 ]
    
    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.
