[PATCH v2 30/70] net/ice/base: fix bit finding range over ptype bitmap

[Qi Zhang <qi.z.zhang@intel.com>]

The 2nd argument to function ice_find_first_bit is the bitmap size,
(in bits) not a mask. Thus, use of UINT16_MAX or 0xFFFF will allow a
potential run off the end of the ptype array.
Also, the ptype bitmap (i.e., prof->ptypes) is declared with size
ICE_FLOW_PTYPE_MAX, thus finding the bits within this bitmap should
not exceed this bound.
