Lidong Chen 86e8f2c4b0 osdep/unix/hostdisk: Fix signed integer overflow ...

The potential overflow issue arises at "size += ret;" because "size"
is of type ssize_t (signed) while "len" is size_t (unsigned). Repeatedly
adding read sizes, "ret", to "size" can potentially exceed the maximum
value of ssize_t, causing it to overflow into a negative or incorrect value.
The fix is to ensure "len" is within the range of SSIZE_MAX.

Fixes: CID 473863
