aarch64: Fix warning in aarch64_ptrue_reg

Browse source 
After r15-4579-g9ffcf1f193b477, we get the following warning/error while bootstrapping on aarch64:
```
../../gcc/gcc/config/aarch64/aarch64.cc: In function ‘rtx_def* aarch64_ptrue_reg(machine_mode, unsigned int)’:
../../gcc/gcc/config/aarch64/aarch64.cc:3643:21: error: comparison of integer expressions of different signedness: ‘int’ and ‘unsigned int’ [-Werror=sign-compare]
 3643 |   for (int i = 0; i < vl; i++)
      |                   ~~^~~~
```

This changes the type of i to unsigned to match the type of vl.

Pushed as obvious after a bootstrap/test on aarch64-linux-gnu.

gcc/ChangeLog:

	* config/aarch64/aarch64.cc (aarch64_ptrue_reg): Fix type
	of induction variable i.
