[PATCH] drivers: target: target_core_transport.c: build warning

[Sudip Mukherjee]

build is giving : 
warning: passing argument 1 of 'strlen' makes pointer from integer 
without a cast [enabled by default]

the snprintf after the strlen is trying to put the "Unsupported" string
at the end of exising string. so len should give the string length here
