btrfs: change BTRFS_MOUNT_* flags to 64bit type
Currently the BTRFS_MOUNT_* flags are already beyond 32 bits, this is
going to cause compilation errors for some 32 bit systems, as their
unsigned long is only 32 bits long, thus flag
BTRFS_MOUNT_IGNORESUPERFLAGS overflows and can lead to errors.
Fix the problem by:
- Migrate all existing BTRFS_MOUNT_* flags to unsigned long long
- Migrate all mount option related variables to unsigned long long
* btrfs_fs_info::mount_opt
* btrfs_fs_context::mount_opt
* mount_opt parameter of btrfs_check_options()
* old_opts parameter of btrfs_remount_begin()
* old_opts parameter of btrfs_remount_cleanup()
* mount_opt parameter of btrfs_check_mountopts_zoned()
* mount_opt and opt parameters of check_ro_option()
