memory allocation without checks

[andreas moroder]

Hello,

I did read Andrew's statement about allocation failures, and I repeat it here

"I'll fix this for the sake of completeness, but please remember that
it is not allocation failures that cause memory leaks. Allocation
failures are *extremely* rare on unix systems. So rare that making an
allocation failure cause a exit(1) would not be completely
unreasonable " ( Andrew Tridgell )

I am sure that is true, but there is NO good reason not to check if it the 
allocation worked or not, so I will continue to post if I find more missing 
checks in HEAD

in libsmb/cli_samr.c   

in the lines 808,809, 815, 876 and 877  there are talloc calls without a check


in libsmb/cli_spoolss.c   most the talloc of info are unchecked.


in utils/smbcacls.c  at line 812 the talloc_init result is unchecked.

int tbd/tdb.c at line 693

realloc is used instead of Realloc and the same pointer is use as result and 
as parameter ( possible cause of leak )

Bye

Andreas
