Since btrfs_read_dev_super() now can distinguish non-btrfs fs and
corrupted superblock thanks for the newly introduced super csum check,
the return value and corresponding error string should also be updated
to print more meaningful errors for end users.

recover_prepare() in chunk-recover.c alloc memory which only contains
sizeof(struct btrfs_super_block). This will cause glibc malloc error
after superblock csum is calculated.

Btrfs has global block reservation, so even mkfs.btrfs can execute
without problem, there is still a possibility that the filesystem can't
be mounted
* (system block group + global block rsv)
and global block rsv = leafsize 10

v2: Use leafsize to get consistent with kernel global_block_rsv
calculation.
v3
in 'btrfs fi df' and if a file/dir
inside a btrfs is given, a warning message will be printed and still
output the disk usage info to keep the old behavior.

When calling find_mount_root(), caller in fact wants to find the mount
point of *BTRFS*.
So also check ent-fstype in find_mount_root() and output proper error
messages if needed.
This will suppress a lot of Inapproiate ioctl for device error
message.
