LU-6722 jbd: double minimum journal size for RHEL7
In RHEL7 (kernel version >= 3.10.0), the maximum journal transaction
size is reduced to half of the RHEL6 case. That may cause Lustre to
complain that the declared transaction credits too large for very
small journal device. This patch increases the minimum journal size
from 4MB to 8MB for RHEL7 case, then counteract the above limitation
about the journal transaction size.
