ima: Set file->f_mode instead of file->f_flags in ima_calc_file_hash()
Commit a408e4a8 ("ima: open a new file instance if no read permissions") tries to create a new file descriptor to calculate a file digest if the file has not been opened with O_RDONLY flag. However, if a new file descriptor cannot be obtained, it sets the FMODE_READ flag to file->f_flags instead of file->f_mode. This patch fixes this issue by replacing f_flags with f_mode as it was before that commit.
