ice: fix usage of logical PF id

In some devices, the function numbers used are non-contiguous. For
example, here is such configuration for E825 device:

root@/home/root# lspci -v | grep Eth
0a:00.0 Ethernet controller: Intel Corporation Ethernet Connection
E825-C for backplane (rev 04)
0a:00.1 Ethernet controller: Intel Corporation Ethernet Connection
E825-C for backplane (rev 04)
0a:00.4 Ethernet controller: Intel Corporation Ethernet Connection
E825-C 10GbE (rev 04)
0a:00.5 Ethernet controller: Intel Corporation Ethernet Connection
E825-C 10GbE (rev 04)

When distributing RSS and FDIR masks, which are global resources across
the active devices, it is required to have a contiguous PF id, which can
be described as a logical PF id. In the case above, function 0 would
have a logical PF id of 0, function 1 would have a logical PF id
of 1, and functions 4 and 5 would have a logical PF ids 2 and 3
respectively.
Using logical PF id can properly describe which slice of resources can
be used by a particular PF.

The 'function id' to 'logical id' mapping has been introduced with the
commit 0153077 ("ice: Support VF queue rate limit and quanta size
configuration"). However, the usage of 'logical_pf_id' field was
unintentionally skipped for profile mask configuration.
Fix it by using 'logical_pf_id' instead of 'pf_id' value when configuring
masks.

Without that patch, wrong indexes, i.e. out of range for given PF, can
be used while configuring resources masks, which might lead to memory
corruption and undefined driver behavior.
