[patch 2.6.26-rc1-git] rndis_host: longer timeout (bugzilla 10590)

[David Brownell <david-b@pacbell.net>]

From: Pierre Ynard <linkfanel@yahoo.fr>

Some devices running some WinCE firmware (with SC_* Samsung processors
according to the SynCE project, verified on a HTC P3600 device) fail to
register because they apparently need extra time to respond correctly
to requests. Increase the existing delay to satisfy them. Based on code
from the SynCE project, on a suggestion of David Brownell.

This patch Works For Me(tm).
