[PATCH] ubifs-utils: common: fix memory leak in devtable.c

[ant.v.moryakov at gmail.com]

From: AntonMoryakov <ant.v.moryakov at gmail.com>

Report of the static analyzer:
Dynamic memory, referenced by 'line', is allocated at devtable.c:356 
by calling function 'getline' and lost at devtable.c:388. 
(line: while (getline(&line, &len, f) != -1) {)

Correct explained:
Now line is freed in any exit scenario via out_close which eliminates this error.

Triggers found by static analyzer Svace.
