[PATCH v2 1/5] IB/hfi1: Move a function from a header file into a .c file

[Bart Van Assche <bvanassche@acm.org>]

Since ib_get_len() only has one caller, move it from a header file into a
.c file. Additionally, remove the superfluous u16 cast. That cast was
introduced by commit 7dafbab3753f ("IB/hfi1: Add functions to parse BTH/IB
headers").
