[ofa-general] [PATCH] ib_mthca: Bring INIT_HCA and other commands timeout into consistency with PRM

[Jack Morgenstein]

Commands INIT_HCA, CLOSE_HCA, SYS_EN, SYS_DIS, and CLOSE_IB all had 1 second
timeouts.  For INIT_HCA this caused problems when had more than 2^18 max qp's
configured.

All other commands have 60-second timeouts.  This patch brings the above commands
into consistency with the rest of the commands.

This patch is an expansion of the INIT_HCA timeout patch submitted by A. Kepner.
