firmware: use 'kernel_read()' to read firmware into kernel buffer
Fengguang correctly points out that the firmware reading should not use vfs_read(), since the buffer is in kernel space. The vfs_read() just happened to work for kernel threads, but sparse warns about the incorrect address spaces, and it's definitely incorrect and could fail for other users of the firmware loading.
