perf units: Fix insufficient array space
[ Upstream commit cf67629f7f637fb988228abdb3aae46d0c1748fe ]
No need to specify the array size, let the compiler figure that out.
This addresses this compiler warning that was noticed while build
testing on fedora rawhide:
31 15.81 fedora:rawhide : FAIL gcc version 15.0.1 20250225 (Red Hat 15.0.1-0) (GCC)
util/units.c: In function 'unit_number__scnprintf':
util/units.c:67:24: error: initializer-string for array of 'char' is too long [-Werror=unterminated-string-initialization]
67 | char unit[4] = "BKMG";
| ^~~~~~
cc1: all warnings being treated as errors
Fixes: 9808143ba2e54818 ("perf tools: Add unit_number__scnprintf function")
