bnxt_en: Use memcpy to copy VPD field info.

bnxt_en: Use memcpy to copy VPD field info.

[ Upstream commit 492adcf481292521ee8df1a482dc12acdb28aa15 ]

Using strlcpy() to copy from VPD is not correct because VPD strings
are not necessarily NULL terminated.  Use memcpy() to copy the VPD
length up to the destination buffer size - 1.  The destination is
zeroed memory so it will always be NULL terminated.
