Remove references to CONTIGMALLOC_WORKS in iflib and em

Description

Remove references to CONTIGMALLOC_WORKS in iflib and em

From Jake:
"The iflib_fl_setup() function tries to pick various buffer sizes based
on the max_frame_size value defined by the parent driver. However, this
code was wrapped under CONTIGMALLOC_WORKS, which was never actually
defined anywhere.

This same code pattern was used in if_em.c, likely trying to match
what iflib uses.

Since CONTIGMALLOC_WORKS is not defined, remove this dead code from
iflib_fl_setup and if_em.c

Given that various iflib drivers appear to be using a similar
calculation, it might be worth making this buffer size a value that the
driver can peek at in the future."
