CIFS: iterate over posix acl xattr entry correctly in ACL_to_cifs_posix()
Commit 2211d5ba5c6c ("posix_acl: xattr representation cleanups")
removes the typedefs and the zero-length a_entries array in struct
posix_acl_xattr_header, and uses bare struct posix_acl_xattr_header
and struct posix_acl_xattr_entry directly.
But it failed to iterate over posix acl slots when converting posix
acls to CIFS format, which results in several test failures in
xfstests (generic/053 generic/105) when testing against a samba v1
server, starting from v4.9-rc1 kernel. e.g.

Fix it by introducing a new "ace" var, like what
cifs_copy_posix_acl() does, and iterating posix acl xattr entries
over it in the for loop.
