Subject: [PATCH] scsi: hpsa: Replace deprecated strncpy() with strscpy_pad()

strncpy() is deprecated for NUL-terminated destination buffers [1].

Replace memset() and strncpy() with strscpy_pad() to copy the version
string and fill the remaining bytes in the destination buffer with NUL
bytes. This avoids zeroing the memory before copying the string.

Compile-tested only.
