net: Return -EINTR when ctrl+c is pressed

Current behavior is that if CTRL+C is pressed command returns 0 that was
successful which is not correct behavior.
The easiest test case is "tftpboot 80000 uImage && echo yes"
and press CTRL+C. Then the second command is called which is incorrect.

Error log:
zynq-uboot> tftpb 80000 uImage && echo yes
