[PATCH 01/26] lib: fwts_acpid: fix checking of return from read()

[Colin King]

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

The return from a read() is of type ssize_t and not size_t and
were are currently checking for n < 0 which will never happen if
n is a size_t type.  So make it ssize_t.
