tools/blktap2: fix build errors caused by Werror in

vhd_journal_write_entry

-O2 -Wall -Werror triggers these warnings:

libvhd-journal.c: In function 'vhd_journal_write_entry':
libvhd-journal.c:335: warning: statement with no effect

Really return the error from vhd_journal_write() to caller.

v2:
 - simplify the patch by just adding the missing return statement
