btrfs-progs: Enhance chunk item validation check

btrfs_check_chunk_valid() doesn't check if
1) chunk flag has conflicting flags
   For example chunk type DATA|METADATA|RAID1|RAID10 is completely
   invalid, while current check_chunk_valid() can't detect it.
2) num_stripes is invalid for RAID10
   Num_stripes 5 is not valid for RAID10.

This patch will enhance btrfs_check_chunk_valid() to handle above cases.
