Subject: [PATCH net] tipc: Remove redundant call to TLV_SPACE()

The purpose of TLV_SPACE() is to add the TLV descriptor size to the size of
the TLV value passed as argument and align the resulting size to
TLV_ALIGNTO.

tipc_tlv_alloc() calls TLV_SPACE() on its argument. In other words,
tipc_tlv_alloc() takes its argument as the size of the TLV value. So the
call to TLV_SPACE() in tipc_get_err_tlv() is redundant. Let's remove this
redundancy.

Fixes: d0796d1ef63d ("tipc: convert legacy nl bearer dump to nl compat")
