vpnor copy_flash: remove incorrect size check

Remove a read window size check, which essentially mandated that a pnor
partition is at least as large as the window size.

To elaborate, the current mbox implementation assumes a read window size
of 1M. This is as per protocol; a host can even send a read size of 0,
the BMC implementation is responsible for reading what's valid and fits
in the window, and inform host about the size read. There was a check
which would see that a read size of 1M past the requested flash offset
is larger than an actual partition file size (for partitions < 1M), and
would fail the read request. Instead, in such a case, read the entire
partition and inform host about the size read.
