fs/dcache: Re-use value stored to dentry->d_flags instead of re-reading
Currently, the __d_clear_type_and_inode() writes the value flags to
dentry->d_flags, then immediately re-reads it in order to use it in a if
statement. This re-read is useless because no other update to
dentry->d_flags can occur at this point.
This commit therefore re-use flags in the if statement instead of
re-reading dentry->d_flags.
