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.
