ubi-utils: ubirsvol: Fix integer overflow in ubirsvol.c
Report of the static analyzer:
The value of an arithmetic expression 'vol_info.leb_size * args.lebs' is a subject to overflow because its operands are not cast to a larger data type before performing arithmetic
Corrections explained:
The fix ensures values are checked before multiplication.
Added casting vol_info.leb_size to long long
Triggers found by static analyzer Svace.
