LU-17566 mdt: remove duplicate call to mdt_init_ucred_reint()

Remove duplicate call to mdt_init_ucred_reint() from
mdt_reint_setxattr().

mdt_init_ucred_reint() is called in mdt_reint_internal() which is
covering all actual reinters. However, SETXATTR was converted to
reinters framework in fd908da and this call was not removed.
So mdt_init_ucred_reint() is called first in mdt_reint_internal() then
again in the specific mdt_reint_setxattr() handler, without anything
special being done on the ucred between them.

Also merge __mdt_init_ucred() and mdt_init_cred() which was
called only once, and with the same prototype.
