strerror: Fix compiler warning "empty expression"

- Remove the final semi-colon in the SEC2TXT() macro definition.

Before:  #define SEC2TXT(sec) case sec: txt = #sec; break;

After:   #define SEC2TXT(sec) case sec: txt = #sec; break

Prior to this change SEC2TXT(foo); would generate break;; which caused
the empty expression warning.
