[B.A.T.M.A.N.] [PATCH] batadv-vis: Avoid file handler leak after failed realloc

[Sven Eckelmann]

The read_file function opens the file and thus has to close the filehandler
after an realloc error. This was forgotten in the fix
0ad384e11ed039d4c3025a7eaf19fe6bcfd41acf ("batadv-vis: Avoid memory leak after
failed realloc").
