Subject: [patch] bfa: use strncpy() instead of memcpy()

BFA_MFG_NAME is "QLogic" which is only 7 bytes, but we are copying 8 bytes.  It's harmless because the badding byte is likely zero but it makes static checkers complain.

Technically the memset() is not needed because strncpy() will pad the rest of the buffer with zeros but I was worried that people would be paranoid.
