[SSSD] [PATCH] LDB_ERR_INVALID_ATTRIBUTE_SYNTAX added to, sysdb_error_to_errno.

[Michal Židek]

If the LDB_ERR_* code is not recognized by sysdb_error_to_errno 
function, it returns EFAULT by default. This caused confusion in the 
case when SSSD tried to store attribute with bad syntax to LDB (like in 
the ticket https://fedorahosted.org/sssd/ticket/1440 ). Error message 
said "Bad address", which was inappropriate.

Patch is in attachment.
