net: tftp: Fix tftp store address check in store_block()
During testing of qemu-riscv32 with a 2GiB memory configuration,
tftp always fails with a error message:
Load address: 0x84000000
Loading: #
TFTP error: trying to overwrite reserved memory...
It turns out the result of 'tftp_load_addr + tftp_load_size' just
overflows (0x100000000) and the test logic in store_block() fails.
Fix this by adjusting the end address to ULONG_MAX when overflow
is detected.
Fixes: a156c47e39ad ("tftp: prevent overwriting reserved memory")
