net: Fix download command parsing
When CONFIG_SYS_HUSH_PARSER is defined network download commands with 1 argument in the format 'tftp "/path/file"' do not work as expected. The hush command parser strips the quotes from "/path/file" which causes the network commands to interpret "/path/file" as an address instead of the intended filename. The previous check for a leading quote in netboot_common() was replaced with a check which ensures only valid numbers are treated as addresses.
