[PATCH] [i-g-t] tests/intel/xe_vm:Reduce n_execs for bind-array-enobufs

The bind-array-enobufs test in xe_vm.c is intended to trigger
an -ENOBUFS error by submitting an oversized bind array.
After encountering and handling the error, the test reduces
n_execs by half and retries the operation. On some environments
with stricter resource limits (e.g. simulator), halving
n_execs isn't sufficient to prevent the ENOBUFS error on the retry.
Reducing n_execs further to n_execs / 4 allows the test to pass
successfully. This patch modifies the test to reduce n_execs
to n_execs / 4 after an ENOBUFS error is handled. This ensures
compatibility with environments that have tighter resource
constraints while maintaining the test's integrity.
