[PATCH 3/9] target: Make helpers non static for EXTENDED_COPY command setup

["Nicholas A. Bellinger" <nab@daterainc.com>]

From: Nicholas Bellinger <nab@daterainc.com>

Both transport_generic_get_mem() and transport_generic_map_mem_to_cmd()
are required by EXTENDED_COPY logic when setting up internally
dispatched command descriptors, so go ahead and make both of these
non static.
