[PATCH] lib: fwts_list: make list creation and initialisation more optimal.

[Colin King]

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

We can just memset() a list structure to initialise it rather than
zero'ing individual members.  Also, when creating a new list struct
we may as well just return the pointer from calloc() rather than
checking for NULL and then returning NULL if calloc() failed.
