[PATCH] lib: fwts_pipeio: zero pollfds to squish a static analysis warning

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

Static analysis is warning that the revents field on pollfd[0] may
be uninitialized.  Although the system call should set this, zero
pollfds to silcence the static analysis warning and also catch any
unforseen poll bugs.

Addresses-Coverity: ("Uninitialized scalar variable")
