Subject[PATCH] selftests/net: initialize char variable to null
Date
char variable in 'so_txtime.c' & 'txtimestamp.c' left uninitilized
by when switch default case taken. raises following warning.

txtimestamp.c:240:2: warning: variable 'tsname' is used uninitialized
whenever switch default is taken [-Wsometimes-uninitialized]

so_txtime.c:210:3: warning: variable 'reason' is used uninitialized
whenever switch default is taken [-Wsometimes-uninitialized]

initialize these variables to NULL to fix this.
