[SRU][N:linux-azure][PATCH 2/2 v2] cifs: make default value of retrans as zero

[John Cabaj]

From: Shyam Prasad N <sprasad at microsoft.com>

BugLink: https://bugs.launchpad.net/bugs/2147347

When retrans mount option was introduced, the default value was set
as 1. However, in the light of some bugs that this has exposed recently
we should change it to 0 and retain the old behaviour before this option
was introduced.
