docs: networking: can: change bcm_msg_head frames member to support flexible array

Browse Source 
[ Upstream commit 641427d5bf ]

The documentation of the 'bcm_msg_head' struct does not match how
it is defined in 'bcm.h'. Changed the frames member to a flexible array,
matching the definition in the header file.

See commit 94dfc73e7c ("treewide: uapi: Replace zero-length arrays with
flexible-array members")
