osc/rdma: bump the default max dynamic attachments to 64
This commit increaes the osc_rdma_max_attach variable from 32 to 64. The new default is kept low due to the small number of registration resources on some systems (Cray Aries). A larger max attachement value can be set by the user on other systems. Signed-off-by: Nathan Hjelm <hjelmn@google.com>
