[PATCH] Bluetooth: btintel_pcie: Use strscpy() instead of strscpy_pad()

[Thorsten Blum]

kzalloc() already zero-initializes the destination buffer 'data', making
strscpy() sufficient for safely copying 'name'. The additional
NUL-padding performed by strscpy_pad() is unnecessary.

Add a new local variable to store the length of 'name' and reuse it
instead of recalculating the same length.
