net: pktgen: add strict buffer parsing index check
Add strict buffer parsing index check to avoid the following Smatch
warning:
net/core/pktgen.c:877 get_imix_entries()
warn: check that incremented offset 'i' is capped
Checking the buffer index i after every get_user/i++ step and returning
with error code immediately avoids the current indirect (but correct)
error handling.
