LU-11389 lnet: increase lnet transaction timeout

Increase the new LNet Health transaction timeout to the original
50s value, to avoid spurious lnet-selftest failures and expected
false timeouts under load.

Fix the lnet_transaction_timeout module parameter description.

Test-Parameters: trivial clientarch=aarch64 testlist=lnet-selftest,lnet-selftest,lnet-selftest,lnet-selftest
Test-Parameters: clientarch=aarch64 testlist=lnet-selftest,lnet-selftest,lnet-selftest,lnet-selftest
