Restoring an incremental level 1 dump will fail with the following error
if the fs uuid of the most recent level 0 dump in the inventory does not
match level 1 dump we are restoring.
xfsrestore: ERROR: selected dump not based on previously applied dump
This can happen when you have multiple filesystems and you are restoring
a level 1 or greater dump of filesystem FS1 but the most recent level 0
dump in the inventory was filesystem FS2
The fix is to ensure the fs uuid of the inventory entry and the dump to
be restored match.

Changelog
V2 wrong file sent
V3
Address review comments from Brian:
fix invmgr_query_all_sessions() returning true if these error cases
persist throughout the loop
make if check more readable and less overloaded in search_inv() and
return an error if GET_REC_NOLOCK() fails
use NULL instead of (uuid_t *)0 in Inv_validate_cmdline()
remove any spaces around braces of code that was changed
