SUNRPC,RPCSEC_GSS: remove unnecessary kmalloc of a checksum
Remove unnecessary kmalloc of temporary space to hold the md5 result; it's small enough to just put on the stack. This code may be called to process rpc's necessary to perform writes, so there's a potential deadlock whenever we kmalloc() here. After this a couple kmalloc()'s still remain, to be removed soon. This also fixes a rare double-free on error noticed by coverity. Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
