bnxt_en: Fix memory fault in bnxt_ethtool_init()
In some firmware images, the length of BNX_DIR_TYPE_PKG_LOG nvram type
could be greater than the fixed buffer length of 4096 bytes allocated by
the driver. This was causing HWRM_NVM_READ to copy more data to the buffer
than the allocated size, causing general protection fault.
Fix the issue by allocating the exact buffer length returned by
HWRM_NVM_FIND_DIR_ENTRY, instead of 4096. Move the kzalloc() call
into the bnxt_get_pkgver() function.
Fixes: 3ebf6f0a09a2 ("bnxt_en: Add installed-package firmware version reporting via Ethtool GDRVINFO")
